11 Rules for Essay Paragraph Structure (with Examples)

How do you structure a paragraph in an essay?

If you’re like the majority of my students, you might be getting your basic essay paragraph structure wrong and getting lower grades than you could!

In this article, I outline the 11 key steps to writing a perfect paragraph. But, this isn’t your normal ‘how to write an essay’ article. Rather, I’ll try to give you some insight into exactly what teachers look out for when they’re grading essays and figuring out what grade to give them.

You can navigate each issue below, or scroll down to read them all:

1. Paragraphs must be at least four sentences long 2. But, at most seven sentences long 3. Your paragraph must be Left-Aligned 4. You need a topic sentence 5 . Next, you need an explanation sentence 6. You need to include an example 7. You need to include citations 8. All paragraphs need to be relevant to the marking criteria 9. Only include one key idea per paragraph 10. Keep sentences short 11. Keep quotes short

Paragraph structure is one of the most important elements of getting essay writing right .

As I cover in my Ultimate Guide to Writing an Essay Plan , paragraphs are the heart and soul of your essay.

However, I find most of my students have either:

• forgotten how to write paragraphs properly,
• gotten lazy, or
• never learned it in the first place!

Paragraphs in essay writing are different from paragraphs in other written genres .

In fact, the paragraphs that you are reading now would not help your grades in an essay.

That’s because I’m writing in journalistic style, where paragraph conventions are vastly different.

For those of you coming from journalism or creative writing, you might find you need to re-learn paragraph writing if you want to write well-structured essay paragraphs to get top grades.

Below are eleven reasons your paragraphs are losing marks, and what to do about it!

Essay Paragraph Structure Rules

1. your paragraphs must be at least 4 sentences long.

In journalism and blog writing, a one-sentence paragraph is great. It’s short, to-the-point, and helps guide your reader. For essay paragraph structure, one-sentence paragraphs suck.

A one-sentence essay paragraph sends an instant signal to your teacher that you don’t have much to say on an issue.

A short paragraph signifies that you know something – but not much about it. A one-sentence paragraph lacks detail, depth and insight.

Many students come to me and ask, “what does ‘add depth’ mean?” It’s one of the most common pieces of feedback you’ll see written on the margins of your essay.

Personally, I think ‘add depth’ is bad feedback because it’s a short and vague comment. But, here’s what it means: You’ve not explained your point enough!

If you’re writing one-, two- or three-sentence essay paragraphs, you’re costing yourself marks.

Always aim for at least four sentences per paragraph in your essays.

This doesn’t mean that you should add ‘fluff’ or ‘padding’ sentences.

Make sure you don’t:

a) repeat what you said in different words, or b) write something just because you need another sentence in there.

But, you need to do some research and find something insightful to add to that two-sentence paragraph if you want to ace your essay.

Check out Points 5 and 6 for some advice on what to add to that short paragraph to add ‘depth’ to your paragraph and start moving to the top of the class.

2. Your Paragraphs must not be more than 7 Sentences Long

Okay, so I just told you to aim for at least four sentences per paragraph. So, what’s the longest your paragraph should be?

Seven sentences. That’s a maximum.

So, here’s the rule:

Between four and seven sentences is the sweet spot that you need to aim for in every single paragraph.

Here’s why your paragraphs shouldn’t be longer than seven sentences:

1. It shows you can organize your thoughts. You need to show your teacher that you’ve broken up your key ideas into manageable segments of text (see point 10)

2. It makes your work easier to read.   You need your writing to be easily readable to make it easy for your teacher to give you good grades. Make your essay easy to read and you’ll get higher marks every time.

One of the most important ways you can make your work easier to read is by writing paragraphs that are less than six sentences long.

3. It prevents teacher frustration. Teachers are just like you. When they see a big block of text their eyes glaze over. They get frustrated, lost, their mind wanders … and you lose marks.

To prevent teacher frustration, you need to ensure there’s plenty of white space in your essay. It’s about showing them that the piece is clearly structured into one key idea per ‘chunk’ of text.

Often, you might find that your writing contains tautologies and other turns of phrase that can be shortened for clarity.

3. Your Paragraph must be Left-Aligned

Turn off ‘Justified’ text and: Never. Turn. It. On. Again.

Justified text is where the words are stretched out to make the paragraph look like a square. It turns the writing into a block. Don’t do it. You will lose marks, I promise you! Win the psychological game with your teacher: left-align your text.

A good essay paragraph is never ‘justified’.

I’m going to repeat this, because it’s important: to prevent your essay from looking like a big block of muddy, hard-to-read text align your text to the left margin only.

You want white space on your page – and lots of it. White space helps your reader scan through your work. It also prevents it from looking like big blocks of text.

You want your reader reading vertically as much as possible: scanning, browsing, and quickly looking through for evidence you’ve engaged with the big ideas.

The justified text doesn’t help you do that. Justified text makes your writing look like a big, lumpy block of text that your reader doesn’t want to read.

What’s wrong with Center-Aligned Text?

While I’m at it, never, ever, center-align your text either. Center-aligned text is impossible to skim-read. Your teacher wants to be able to quickly scan down the left margin to get the headline information in your paragraph.

Not many people center-align text, but it’s worth repeating: never, ever center-align your essays.

Don’t annoy your reader. Left align your text.

4. Your paragraphs must have a Topic Sentence

The first sentence of an essay paragraph is called the topic sentence. This is one of the most important sentences in the correct essay paragraph structure style.

The topic sentence should convey exactly what key idea you’re going to cover in your paragraph.

Too often, students don’t let their reader know what the key idea of the paragraph is until several sentences in.

You must show what the paragraph is about in the first sentence.

You never, ever want to keep your reader in suspense. Essays are not like creative writing. Tell them straight away what the paragraph is about. In fact, if you can, do it in the first half of the first sentence .

I’ll remind you again: make it easy to grade your work. Your teacher is reading through your work trying to determine what grade to give you. They’re probably going to mark 20 assignments in one sitting. They have no interest in storytelling or creativity. They just want to know how much you know! State what the paragraph is about immediately and move on.

Suggested: Best Words to Start a Paragraph

Ideal Essay Paragraph Structure Example: Writing a Topic Sentence If your paragraph is about how climate change is endangering polar bears, say it immediately : “Climate change is endangering polar bears.” should be your first sentence in your paragraph. Take a look at first sentence of each of the four paragraphs above this one. You can see from the first sentence of each paragraph that the paragraphs discuss:

When editing your work, read each paragraph and try to distil what the one key idea is in your paragraph. Ensure that this key idea is mentioned in the first sentence .

(Note: if there’s more than one key idea in the paragraph, you may have a problem. See Point 9 below .)

The topic sentence is the most important sentence for getting your essay paragraph structure right. So, get your topic sentences right and you’re on the right track to a good essay paragraph.

5. You need an Explanation Sentence

All topic sentences need a follow-up explanation. The very first point on this page was that too often students write paragraphs that are too short. To add what is called ‘depth’ to a paragraph, you can come up with two types of follow-up sentences: explanations and examples.

Let’s take explanation sentences first.

Explanation sentences give additional detail. They often provide one of the following services:

Let’s go back to our example of a paragraph on Climate change endangering polar bears. If your topic sentence is “Climate change is endangering polar bears.”, then your follow-up explanation sentence is likely to explain how, why, where, or when. You could say:

Ideal Essay Paragraph Structure Example: Writing Explanation Sentences 1. How: “The warming atmosphere is melting the polar ice caps.” 2. Why: “The polar bears’ habitats are shrinking every single year.” 3. Where: “This is happening in the Antarctic ice caps near Greenland.” 4. When: “Scientists first noticed the ice caps were shrinking in 1978.”

You don’t have to provide all four of these options each time.

But, if you’re struggling to think of what to add to your paragraph to add depth, consider one of these four options for a good quality explanation sentence.

6. Your need to Include an Example

Examples matter! They add detail. They also help to show that you genuinely understand the issue. They show that you don’t just understand a concept in the abstract; you also understand how things work in real life.

Example sentences have the added benefit of personalising an issue. For example, after saying “Polar bears’ habitats are shrinking”, you could note specific habitats, facts and figures, or even a specific story about a bear who was impacted.

Ideal Essay Paragraph Structure Example: Writing an ‘Example’ Sentence “For example, 770,000 square miles of Arctic Sea Ice has melted in the past four decades, leading Polar Bear populations to dwindle ( National Geographic, 2018 )

In fact, one of the most effective politicians of our times – Barrack Obama – was an expert at this technique. He would often provide examples of people who got sick because they didn’t have healthcare to sell Obamacare.

What effect did this have? It showed the real-world impact of his ideas. It humanised him, and got him elected president – twice!

Be like Obama. Provide examples. Often.

7. All Paragraphs need Citations

Provide a reference to an academic source in every single body paragraph in the essay. The only two paragraphs where you don’t need a reference is the introduction and conclusion .

Let me repeat: Paragraphs need at least one reference to a quality scholarly source .

Let me go even further:

Students who get the best marks provide two references to two different academic sources in every paragraph.

Two references in a paragraph show you’ve read widely, cross-checked your sources, and given the paragraph real thought.

It’s really important that these references link to academic sources, not random websites, blogs or YouTube videos. Check out our Seven Best types of Sources to Cite in Essays post to get advice on what sources to cite. Number 6 w ill surprise you!

Ideal Essay Paragraph Structure Example: In-Text Referencing in Paragraphs Usually, in-text referencing takes the format: (Author, YEAR), but check your school’s referencing formatting requirements carefully. The ‘Author’ section is the author’s last name only. Not their initials. Not their first name. Just their last name . My name is Chris Drew. First name Chris, last name Drew. If you were going to reference an academic article I wrote in 2019, you would reference it like this: (Drew, 2019).

Where do you place those two references?

Place the first reference at the end of the first half of the paragraph. Place the second reference at the end of the second half of the paragraph.

This spreads the references out and makes it look like all the points throughout the paragraph are backed up by your sources. The goal is to make it look like you’ve reference regularly when your teacher scans through your work.

Remember, teachers can look out for signposts that indicate you’ve followed academic conventions and mentioned the right key ideas.

Spreading your referencing through the paragraph helps to make it look like you’ve followed the academic convention of referencing sources regularly.

Here are some examples of how to reference twice in a paragraph:

• If your paragraph was six sentences long, you would place your first reference at the end of the third sentence and your second reference at the end of the sixth sentence.
• If your paragraph was five sentences long, I would recommend placing one at the end of the second sentence and one at the end of the fifth sentence.

You’ve just read one of the key secrets to winning top marks.

8. Every Paragraph must be relevant to the Marking Criteria

Every paragraph must win you marks. When you’re editing your work, check through the piece to see if every paragraph is relevant to the marking criteria.

For the British: In the British university system (I’m including Australia and New Zealand here – I’ve taught at universities in all three countries), you’ll usually have a ‘marking criteria’. It’s usually a list of between two and six key learning outcomes your teacher needs to use to come up with your score. Sometimes it’s called a:

• Marking criteria
• Marking rubric
• (Key) learning outcome
• Indicative content

Check your assignment guidance to see if this is present. If so, use this list of learning outcomes to guide what you write. If your paragraphs are irrelevant to these key points, delete the paragraph .

Paragraphs that don’t link to the marking criteria are pointless. They won’t win you marks.

For the Americans: If you don’t have a marking criteria / rubric / outcomes list, you’ll need to stick closely to the essay question or topic. This goes out to those of you in the North American system. North America (including USA and Canada here) is often less structured and the professor might just give you a topic to base your essay on.

If all you’ve got is the essay question / topic, go through each paragraph and make sure each paragraph is relevant to the topic.

For example, if your essay question / topic is on “The Effects of Climate Change on Polar Bears”,

• Don’t talk about anything that doesn’t have some connection to climate change and polar bears;
• Don’t talk about the environmental impact of oil spills in the Gulf of Carpentaria;
• Don’t talk about black bear habitats in British Columbia.
• Do talk about the effects of climate change on polar bears (and relevant related topics) in every single paragraph .

You may think ‘stay relevant’ is obvious advice, but at least 20% of all essays I mark go off on tangents and waste words.

Stay on topic in Every. Single. Paragraph. If you want to learn more about how to stay on topic, check out our essay planning guide .

9. Only have one Key Idea per Paragraph

One key idea for each paragraph. One key idea for each paragraph. One key idea for each paragraph.

Don’t forget!

Too often, a student starts a paragraph talking about one thing and ends it talking about something totally different. Don’t be that student.

To ensure you’re focussing on one key idea in your paragraph, make sure you know what that key idea is. It should be mentioned in your topic sentence (see Point 3 ). Every other sentence in the paragraph adds depth to that one key idea.

If you’ve got sentences in your paragraph that are not relevant to the key idea in the paragraph, they don’t fit. They belong in another paragraph.

Go through all your paragraphs when editing your work and check to see if you’ve veered away from your paragraph’s key idea. If so, you might have two or even three key ideas in the one paragraph.

You’re going to have to get those additional key ideas, rip them out, and give them paragraphs of their own.

If you have more than one key idea in a paragraph you will lose marks. I promise you that.

The paragraphs will be too hard to read, your reader will get bogged down reading rather than scanning, and you’ll have lost grades.

10. Keep Sentences Short

If a sentence is too long it gets confusing. When the sentence is confusing, your reader will stop reading your work. They will stop reading the paragraph and move to the next one. They’ll have given up on your paragraph.

Short, snappy sentences are best.

Shorter sentences are easier to read and they make more sense. Too often, students think they have to use big, long, academic words to get the best marks. Wrong. Aim for clarity in every sentence in the paragraph. Your teacher will thank you for it.

The students who get the best marks write clear, short sentences.

When editing your draft, go through your essay and see if you can shorten your longest five sentences.

(To learn more about how to write the best quality sentences, see our page on Seven ways to Write Amazing Sentences .)

11. Keep Quotes Short

Eighty percent of university teachers hate quotes. That’s not an official figure. It’s my guestimate based on my many interactions in faculty lounges. Twenty percent don’t mind them, but chances are your teacher is one of the eight out of ten who hate quotes.

Teachers tend to be turned off by quotes because it makes it look like you don’t know how to say something on your own words.

Now that I’ve warned you, here’s how to use quotes properly:

Ideal Essay Paragraph Structure Example: How To Use Quotes in University-Level Essay Paragraphs 1. Your quote should be less than one sentence long. 2. Your quote should be less than one sentence long. 3. You should never start a sentence with a quote. 4. You should never end a paragraph with a quote. 5 . You should never use more than five quotes per essay. 6. Your quote should never be longer than one line in a paragraph.

The minute your teacher sees that your quote takes up a large chunk of your paragraph, you’ll have lost marks.

Your teacher will circle the quote, write a snarky comment in the margin, and not even bother to give you points for the key idea in the paragraph.

Avoid quotes, but if you really want to use them, follow those five rules above.

I’ve also provided additional pages outlining Seven tips on how to use Quotes if you want to delve deeper into how, when and where to use quotes in essays. Be warned: quoting in essays is harder than you thought.

Follow the advice above and you’ll be well on your way to getting top marks at university.

4 thoughts on “11 Rules for Essay Paragraph Structure (with Examples)”

Hello there. I noticed that throughout this article on Essay Writing, you keep on saying that the teacher won’t have time to go through the entire essay. Don’t you think this is a bit discouraging that with all the hard work and time put into your writing, to know that the teacher will not read through the entire paper?

Hi Clarence,

Thanks so much for your comment! I love to hear from readers on their thoughts.

Yes, I agree that it’s incredibly disheartening.

But, I also think students would appreciate hearing the truth.

Behind closed doors many / most university teachers are very open about the fact they ‘only have time to skim-read papers’. They regularly bring this up during heated faculty meetings about contract negotiations! I.e. in one university I worked at, we were allocated 45 minutes per 10,000 words – that’s just over 4 minutes per 1,000 word essay, and that’d include writing the feedback, too!

If students know the truth, they can better write their essays in a way that will get across the key points even from a ‘skim-read’.

I hope to write candidly on this website – i.e. some of this info will never be written on university blogs because universities want to hide these unfortunate truths from students.

Thanks so much for stopping by!

Regards, Chris

This is wonderful and helpful, all I say is thank you very much. Because I learned a lot from this site, own by chris thank you Sir.

Thank you. This helped a lot.

What this handout is about

This handout will help you understand how paragraphs are formed, how to develop stronger paragraphs, and how to completely and clearly express your ideas.

What is a paragraph?

Paragraphs are the building blocks of papers. Many students define paragraphs in terms of length: a paragraph is a group of at least five sentences, a paragraph is half a page long, etc. In reality, though, the unity and coherence of ideas among sentences is what constitutes a paragraph. A paragraph is defined as “a group of sentences or a single sentence that forms a unit” (Lunsford and Connors 116). Length and appearance do not determine whether a section in a paper is a paragraph. For instance, in some styles of writing, particularly journalistic styles, a paragraph can be just one sentence long. Ultimately, a paragraph is a sentence or group of sentences that support one main idea. In this handout, we will refer to this as the “controlling idea,” because it controls what happens in the rest of the paragraph.

How do I decide what to put in a paragraph?

Before you can begin to determine what the composition of a particular paragraph will be, you must first decide on an argument and a working thesis statement for your paper. What is the most important idea that you are trying to convey to your reader? The information in each paragraph must be related to that idea. In other words, your paragraphs should remind your reader that there is a recurrent relationship between your thesis and the information in each paragraph. A working thesis functions like a seed from which your paper, and your ideas, will grow. The whole process is an organic one—a natural progression from a seed to a full-blown paper where there are direct, familial relationships between all of the ideas in the paper.

The decision about what to put into your paragraphs begins with the germination of a seed of ideas; this “germination process” is better known as brainstorming . There are many techniques for brainstorming; whichever one you choose, this stage of paragraph development cannot be skipped. Building paragraphs can be like building a skyscraper: there must be a well-planned foundation that supports what you are building. Any cracks, inconsistencies, or other corruptions of the foundation can cause your whole paper to crumble.

So, let’s suppose that you have done some brainstorming to develop your thesis. What else should you keep in mind as you begin to create paragraphs? Every paragraph in a paper should be :

• Unified : All of the sentences in a single paragraph should be related to a single controlling idea (often expressed in the topic sentence of the paragraph).
• Clearly related to the thesis : The sentences should all refer to the central idea, or thesis, of the paper (Rosen and Behrens 119).
• Coherent : The sentences should be arranged in a logical manner and should follow a definite plan for development (Rosen and Behrens 119).
• Well-developed : Every idea discussed in the paragraph should be adequately explained and supported through evidence and details that work together to explain the paragraph’s controlling idea (Rosen and Behrens 119).

How do I organize a paragraph?

There are many different ways to organize a paragraph. The organization you choose will depend on the controlling idea of the paragraph. Below are a few possibilities for organization, with links to brief examples:

• Narration : Tell a story. Go chronologically, from start to finish. ( See an example. )
• Description : Provide specific details about what something looks, smells, tastes, sounds, or feels like. Organize spatially, in order of appearance, or by topic. ( See an example. )
• Process : Explain how something works, step by step. Perhaps follow a sequence—first, second, third. ( See an example. )
• Classification : Separate into groups or explain the various parts of a topic. ( See an example. )
• Illustration : Give examples and explain how those examples support your point. (See an example in the 5-step process below.)

Illustration paragraph: a 5-step example

From the list above, let’s choose “illustration” as our rhetorical purpose. We’ll walk through a 5-step process for building a paragraph that illustrates a point in an argument. For each step there is an explanation and example. Our example paragraph will be about human misconceptions of piranhas.

Step 1. Decide on a controlling idea and create a topic sentence

Paragraph development begins with the formulation of the controlling idea. This idea directs the paragraph’s development. Often, the controlling idea of a paragraph will appear in the form of a topic sentence. In some cases, you may need more than one sentence to express a paragraph’s controlling idea.

Controlling idea and topic sentence — Despite the fact that piranhas are relatively harmless, many people continue to believe the pervasive myth that piranhas are dangerous to humans.

Step 2. Elaborate on the controlling idea

Paragraph development continues with an elaboration on the controlling idea, perhaps with an explanation, implication, or statement about significance. Our example offers a possible explanation for the pervasiveness of the myth.

Elaboration — This impression of piranhas is exacerbated by their mischaracterization in popular media.

Step 3. Give an example (or multiple examples)

Paragraph development progresses with an example (or more) that illustrates the claims made in the previous sentences.

Example — For example, the promotional poster for the 1978 horror film Piranha features an oversized piranha poised to bite the leg of an unsuspecting woman.

Step 4. Explain the example(s)

The next movement in paragraph development is an explanation of each example and its relevance to the topic sentence. The explanation should demonstrate the value of the example as evidence to support the major claim, or focus, in your paragraph.

Continue the pattern of giving examples and explaining them until all points/examples that the writer deems necessary have been made and explained. NONE of your examples should be left unexplained. You might be able to explain the relationship between the example and the topic sentence in the same sentence which introduced the example. More often, however, you will need to explain that relationship in a separate sentence.

Explanation for example — Such a terrifying representation easily captures the imagination and promotes unnecessary fear.

Notice that the example and explanation steps of this 5-step process (steps 3 and 4) can be repeated as needed. The idea is that you continue to use this pattern until you have completely developed the main idea of the paragraph.

Step 5. Complete the paragraph’s idea or transition into the next paragraph

The final movement in paragraph development involves tying up the loose ends of the paragraph. At this point, you can remind your reader about the relevance of the information to the larger paper, or you can make a concluding point for this example. You might, however, simply transition to the next paragraph.

Sentences for completing a paragraph — While the trope of the man-eating piranhas lends excitement to the adventure stories, it bears little resemblance to the real-life piranha. By paying more attention to fact than fiction, humans may finally be able to let go of this inaccurate belief.

Finished paragraph

Despite the fact that piranhas are relatively harmless, many people continue to believe the pervasive myth that piranhas are dangerous to humans. This impression of piranhas is exacerbated by their mischaracterization in popular media. For example, the promotional poster for the 1978 horror film Piranha features an oversized piranha poised to bite the leg of an unsuspecting woman. Such a terrifying representation easily captures the imagination and promotes unnecessary fear. While the trope of the man-eating piranhas lends excitement to the adventure stories, it bears little resemblance to the real-life piranha. By paying more attention to fact than fiction, humans may finally be able to let go of this inaccurate belief.

Troubleshooting paragraphs

Problem: the paragraph has no topic sentence.

Imagine each paragraph as a sandwich. The real content of the sandwich—the meat or other filling—is in the middle. It includes all the evidence you need to make the point. But it gets kind of messy to eat a sandwich without any bread. Your readers don’t know what to do with all the evidence you’ve given them. So, the top slice of bread (the first sentence of the paragraph) explains the topic (or controlling idea) of the paragraph. And, the bottom slice (the last sentence of the paragraph) tells the reader how the paragraph relates to the broader argument. In the original and revised paragraphs below, notice how a topic sentence expressing the controlling idea tells the reader the point of all the evidence.

Original paragraph

Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. If the fish are well-fed, they won’t bite humans.

Revised paragraph

Although most people consider piranhas to be quite dangerous, they are, for the most part, entirely harmless. Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. If the fish are well-fed, they won’t bite humans.

Once you have mastered the use of topic sentences, you may decide that the topic sentence for a particular paragraph really shouldn’t be the first sentence of the paragraph. This is fine—the topic sentence can actually go at the beginning, middle, or end of a paragraph; what’s important is that it is in there somewhere so that readers know what the main idea of the paragraph is and how it relates back to the thesis of your paper. Suppose that we wanted to start the piranha paragraph with a transition sentence—something that reminds the reader of what happened in the previous paragraph—rather than with the topic sentence. Let’s suppose that the previous paragraph was about all kinds of animals that people are afraid of, like sharks, snakes, and spiders. Our paragraph might look like this (the topic sentence is bold):

Like sharks, snakes, and spiders, piranhas are widely feared. Although most people consider piranhas to be quite dangerous, they are, for the most part, entirely harmless . Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. If the fish are well-fed, they won’t bite humans.

Problem: the paragraph has more than one controlling idea

If a paragraph has more than one main idea, consider eliminating sentences that relate to the second idea, or split the paragraph into two or more paragraphs, each with only one main idea. Watch our short video on reverse outlining to learn a quick way to test whether your paragraphs are unified. In the following paragraph, the final two sentences branch off into a different topic; so, the revised paragraph eliminates them and concludes with a sentence that reminds the reader of the paragraph’s main idea.

Although most people consider piranhas to be quite dangerous, they are, for the most part, entirely harmless. Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. A number of South American groups eat piranhas. They fry or grill the fish and then serve them with coconut milk or tucupi, a sauce made from fermented manioc juices.

Problem: transitions are needed within the paragraph

You are probably familiar with the idea that transitions may be needed between paragraphs or sections in a paper (see our handout on transitions ). Sometimes they are also helpful within the body of a single paragraph. Within a paragraph, transitions are often single words or short phrases that help to establish relationships between ideas and to create a logical progression of those ideas in a paragraph. This is especially likely to be true within paragraphs that discuss multiple examples. Let’s take a look at a version of our piranha paragraph that uses transitions to orient the reader:

Although most people consider piranhas to be quite dangerous, they are, except in two main situations, entirely harmless. Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ instinct is to flee, not attack. But there are two situations in which a piranha bite is likely. The first is when a frightened piranha is lifted out of the water—for example, if it has been caught in a fishing net. The second is when the water level in pools where piranhas are living falls too low. A large number of fish may be trapped in a single pool, and if they are hungry, they may attack anything that enters the water.

In this example, you can see how the phrases “the first” and “the second” help the reader follow the organization of the ideas in the paragraph.

The Ultimate Guide to the 5-Paragraph Essay

A five-paragraph essay is a prose composition that follows a prescribed format of an introductory paragraph, three body paragraphs, and a concluding paragraph, and is typically taught during primary English education and applied on standardized testing throughout schooling.

Learning to write a high-quality five-paragraph essay is an essential skill for students in early English classes as it allows them to express certain ideas, claims, or concepts in an organized manner, complete with evidence that supports each of these notions. Later, though, students may decide to stray from the standard five-paragraph format and venture into writing an  exploratory essay  instead.

Still, teaching students to organize essays into the five-paragraph format is an easy way to introduce them to writing literary criticism, which will be tested time and again throughout their primary, secondary, and further education.

Writing a Good Introduction

The introduction is the first paragraph in your essay, and it should accomplish a few specific goals: capture the reader's interest, introduce the topic, and make a claim or express an opinion in a thesis statement.

It's a good idea to start your essay with a hook (fascinating statement) to pique the reader's interest, though this can also be accomplished by using descriptive words, an anecdote, an intriguing question, or an interesting fact. Students can practice with creative writing prompts to get some ideas for interesting ways to start an essay.

The next few sentences should explain your first statement, and prepare the reader for your thesis statement, which is typically the last sentence in the introduction. Your  thesis sentence  should provide your specific assertion and convey a clear point of view, which is typically divided into three distinct arguments that support this assertation, which will each serve as central themes for the body paragraphs.

Writing Body Paragraphs

The body of the essay will include three body paragraphs in a five-paragraph essay format, each limited to one main idea that supports your thesis.

To correctly write each of these three body paragraphs, you should state your supporting idea, your topic sentence, then back it up with two or three sentences of evidence. Use examples that validate the claim before concluding the paragraph and using transition words to lead to the paragraph that follows — meaning that all of your body paragraphs should follow the pattern of "statement, supporting ideas, transition statement."

Words to use as you transition from one paragraph to another include: moreover, in fact, on the whole, furthermore, as a result, simply put, for this reason, similarly, likewise, it follows that, naturally, by comparison, surely, and yet.

Writing a Conclusion

The final paragraph will summarize your main points and re-assert your main claim (from your thesis sentence). It should point out your main points, but should not repeat specific examples, and should, as always, leave a lasting impression on the reader.

The first sentence of the conclusion, therefore, should be used to restate the supporting claims argued in the body paragraphs as they relate to the thesis statement, then the next few sentences should be used to explain how the essay's main points can lead outward, perhaps to further thought on the topic. Ending the conclusion with a question, anecdote, or final pondering is a great way to leave a lasting impact.

Once you complete the first draft of your essay, it's a good idea to re-visit the thesis statement in your first paragraph. Read your essay to see if it flows well, and you might find that the supporting paragraphs are strong, but they don't address the exact focus of your thesis. Simply re-write your thesis sentence to fit your body and summary more exactly, and adjust the conclusion to wrap it all up nicely.

Practice Writing a Five-Paragraph Essay

Students can use the following steps to write a standard essay on any given topic. First, choose a topic, or ask your students to choose their topic, then allow them to form a basic five-paragraph by following these steps:

• Decide on your  basic thesis , your idea of a topic to discuss.
• Decide on three pieces of supporting evidence you will use to prove your thesis.
• Write an introductory paragraph, including your thesis and evidence (in order of strength).
• Write your first body paragraph, starting with restating your thesis and focusing on your first piece of supporting evidence.
• End your first paragraph with a transitional sentence that leads to the next body paragraph.
• Write paragraph two of the body focussing on your second piece of evidence. Once again make the connection between your thesis and this piece of evidence.
• End your second paragraph with a transitional sentence that leads to paragraph number three.
• Repeat step 6 using your third piece of evidence.
• Begin your concluding paragraph by restating your thesis. Include the three points you've used to prove your thesis.
• End with a punch, a question, an anecdote, or an entertaining thought that will stay with the reader.

Once a student can master these 10 simple steps, writing a basic five-paragraph essay will be a piece of cake, so long as the student does so correctly and includes enough supporting information in each paragraph that all relate to the same centralized main idea, the thesis of the essay.

Limitations of the Five-Paragraph Essay

The five-paragraph essay is merely a starting point for students hoping to express their ideas in academic writing; there are some other forms and styles of writing that students should use to express their vocabulary in the written form.

According to Tory Young's "Studying English Literature: A Practical Guide":

"Although school students in the U.S. are examined on their ability to write a  five-paragraph essay , its  raison d'être  is purportedly to give practice in basic writing skills that will lead to future success in more varied forms. Detractors feel, however, that writing to rule in this way is more likely to discourage imaginative writing and thinking than enable it. . . . The five-paragraph essay is less aware of its  audience  and sets out only to present information, an account or a kind of story rather than explicitly to persuade the reader."

Students should instead be asked to write other forms, such as journal entries, blog posts, reviews of goods or services, multi-paragraph research papers, and freeform expository writing around a central theme. Although five-paragraph essays are the golden rule when writing for standardized tests, experimentation with expression should be encouraged throughout primary schooling to bolster students' abilities to utilize the English language fully.

What is a paragraph.

A paragraph is a series of sentences on a specific point or topic.  A well written paragraph must have a topic sentence which states the main idea: what the paragraph is about.  While some say the  topic sentence can be anywhere in the paragraph, it is best to put it as the first sentence in a paragraph.  The rest of the sentences in the paragraph support, elaborate, and/or further explain the main idea expressed in the topic sentence.

Paragraphs have varying length depending upon various factors.  An average paragraph in an academic essay is about six to eight sentences.

Types of Paragraphs

There are various types of paragraphs such as summaries, abstracts, and answers to questions for a specific assignment.  In addition, there are specialized types of paragraphs for various reports such as feasibility studies or performance reports.

The types of paragraphs covered in this lesson are general paragraphs as would be used in the body of a letter or an academic essay, including general research papers (research essays).

Parts of a Paragraph

Topic sentence – purpose of a paragraph.

Unless you are writing specialized report such as a scientific research paper or a feasibility study that may otherwise show the purpose of a paragraph such as a heading , a well written paragraph must have a topic sentence which states what the paragraph is about.

Whether you are writing a paragraph for a specific assignment, an academic essay, a research paper, or a simple letter, each paragraph

The topic sentence should be the first sentence of the paragraph so that the reader knows what the paragraph is about.  The topic sentence in a body paragraph of an essay must be support for the thesis: a reason why the thesis is true or accurate.

The rest of the sentences in the paragraph of an essay support, elaborate, and/or further explain the topic sentence.

Here is an example of a paragraph:

The first sentence is the topic sentence. See how the rest of the sentences support, elaborate, and/or or further explain it.

Almost every aspect of modern life has been improved through convenience provided by technology.    From the alarm clock in the morning to the entertainment center at night, everyday life is improved.  The automatic coffee maker has the coffee ready at a certain time. Cars or public transportation bring people to work where computers operate at the push of a button.  At home, there’s the convenience of washing machines and dryers, dishwashers, air conditioners, and power lawn mowers.  Modern technology has made life better with many conveniences.

Everything in this paragraph is about how modern life has been improved through convenience provided by technology.

Unity and Coherence

A paragraph must have unity.

All of the sentences of a particular paragraph must focus on one point to achieve one goal: to support the topic sentence.

A paragraph must have coherence.

The sentences must flow smoothly and logically from one to the next as they support the topic sentence.

The last sentence of the paragraph should restate the topic sentence to help achieve unity and coherence.

Here is an example with information that  does not  support the topic sentence.

Almost every aspect of modern life has been improved through convenience provided by modern technology.  From the alarm clock in the morning to the entertainment center at night, everyday life is improved. The automatic coffee maker has the coffee ready at a certain time. People are more concerned about health issues and good air quality, so they have started walking or riding a bike to work even though they have the option of using a car or public transportation.   There’s the convenience of washing machines and dryers, dishwashers, air conditioners, and power lawn mowers.  Modern technology has made life better with many conveniences.

See how just one non-supporting sentence takes away from the effectiveness of the paragraph in showing how modern conveniences make life better since the unity and coherence are affected.  There is no longer unity among all the sentences.  The thought pattern is disjointed and the paragraph loses its coherence.

Here’s another example of a paragraph

Not only has modern technology improved life through convenience, it has improved life through efficiency.  The time saved with machines doing most of the work leaves more time for people to develop their personal goals or to just relax.  Years ago, when doing laundry could take all day, there wasn’t time left over to read or go to school or even just to take a leisurely walk.  Nowadays, people have more time and energy than ever to simply enjoy their lives thanks to the efficiency of modern technology.

Note: See how all the sentences work together to support the point that technology has improved lives through efficiency.

Transitions – Words that Connect

Transitions  are words, groups of words, or sentences that connect one sentence to another or one paragraph to another.

They promote a logical flow from one idea to the next.

While they are not needed in every sentence, they are missed when they are omitted since the flow of thoughts becomes disjointed or even confusing.

There are different types of transitions such as the following:

• Time – before, after, during, in the meantime, nowadays
• Space – over, around, under
• Examples – for instance, one example is
• Comparison –  on the other hand, the opposing view
• Consequence – as a result, subsequently

These are just a few examples.  The idea is to paint a clear, logical connection between sentences and between paragraphs.

Here’s how transitions help make a paragraph unified and coherent

Not only  has modern technology improved life through convenience, it has improved life through efficiency.  The time saved with machines doing most of the work leaves more time for people to develop their personal goals or to just relax.   Years ago,  when doing laundry could take all day, there wasn’t time left over to read or go to school or even just to take a leisurely walk.   Nowadays , people have more time and energy than ever to simply enjoy their lives thanks to the efficiency of modern technology.

Each part of a paragraph must support the topic sentence.  In addition, the sentences must flow logically from one to the other.

See how the following paragraph has ideas that don’t seem to belong

Growing flowers is fun.  The sun rises in the morning and warms the soil.  Flowers come in all different sizes, shapes, and colors.  Sometimes, there is not enough rain.  Flowers also bloom during different times of the year.  Flowers need nutrients to grow strong and beautiful.  There are some children who like to pick the flowers. There are different growing seasons in different parts of the country.  Flowers that will grow high should be planted behind those that will not grow as high.  Some people let their dog’s leash extend allowing the dog to go into the flower beds which is not very nice. Designing a flower bed has to consider the different times the flowers will bloom.  A substitute for rainfall should be planned.  It is fun to grow flowers.

Here is a revised version with unity and coherence.  See how each sentence is clearly part of the whole which is to show how it is fun to grow flowers.

Growing flowers is fun.   Planning the garden is the first step, and it is part of the fun.  Flowers must be selected for their size, color, and time of bloom.  Selections should be made so that there is at least one type of flower blooming throughout the season and that taller flowers are behind shorter ones.  Meeting the challenges to assure growth such as with an irrigation system or hand watering and fertilizing when needed is also part of the fun.   It’s wonderful to check the garden every day to see the little green sprouts starting to appear.  It gives a great sense of accomplishment and joy to see the flowers in bloom.  It is fun to grow flowers.

An example of a paragraph from a business letter  which does  have unity and coherence:

There are several reasons to select my company to do this job.  We are a family owned and operated business and have been in business in this county for thirty-five years.  In addition to thousands of satisfied customers, we have proudly sponsored many community events and organizations.  All of our employees live in this county, and most have stayed with us for years.  We have successfully kept our overhead low and pass those savings onto our customers.  By far, we are the best company to complete this project.

Note: See how all the sentences work together to support the point that we are the best company to hire.

Here’s a version of the paragraph which  does not  have unity and coherence:

I am happy that the warm weather is finally here! It’s been a cold winter. There are several reasons to select my company to do this job.  By far, we are the best company to complete this project.  I have a large family, and in addition to having Sunday dinners, we work together in the company which has many satisfied customers.  Some of my employees take the bus to work, so I am concerned about our public transportation system.  We have proudly served our community, and we use cost saving methods to keep prices low.

An example of a paragraph in an inter-office memo

Beginning January 1, we will have a revised policy concerning new customers.  The updated intake form includes additional information, so please be sure to read through and complete each section.  Pay particular addition to the additional questions at the bottom as they are now required by the insurance company.  We would like to have e-mail addresses as well.  You can assure customers that we will not be sending them solicitations nor giving the list to any other business.  Be sure to fill in the information neatly and accurately. It is preferred that the information be entered directly into the computer although we realize there are times when that is not practical and a hard-copy form will have to be completed by hand.  Review the instructions on the back page of the form for more details on the revised policy for new customers.

Note:  See how all the sentences work together to support the point shown in the topic sentence that modern technology has expanded accessibility.

Closing/Transitional Statements in Paragraphs

The last sentence of a paragraph should remind the reader of the point of the paragraph and transition into the next paragraph if there is one.  See how the last sentence, for example, in the above paragraph reminds the reader of what the paragraph is about: Review the instructions on the back page of the form for more details on the revised policy for new customers.

Multi-Paragraph Documents

Most paragraphs we see are part of a multi-paragraph document: newspaper and magazine articles, books, business letters and inter-office memorandum, “how-to” documents, and other informational documents.  Usually, there is an organization of the paragraphs in a specific way.  The opening paragraph generally gives some idea of what the document is about.  The middle paragraphs give more details about the specific point.  The last paragraph ends the writing, generally by summing up and repeating the point.

There are some context-specific documents that have moe clearly defined paragraphs which are something included as sections of the writing.  For example, a feasibility report might have paragraphs as follows: abstract and/or summary, introduction, discussion, conclusion, recommendations.

Paragraphs in Business Letters and Inter-Office Memorandum

Business letters and inter-office memoradums basically have the same organization of the content:  an introduction paragraph, paragraphs that prove or further explain, and a concluding paragraph which sums up and repeats the point.  A business letter, however, is generally written on company stationery and has the date and address block in the upper left, a Re: line, a salutation such as Dear Mr. Haller (although some are no longer using a formal salutation), and a complimentary closing such as Sincerely.    An inter-office memorandum is generally written on plain paper, sometimes with the company logo as part of the template, lines with To:, From:, Date:, and Re: in the upper left, and no complimentary closing.

Paragraphs in Informational Documents and Academic Essays

Informational documents.

This refers to groups of writings that are designed to give information about a topic or position on a topic.  While they all include a specific thesis (point), have an introduction and concluding paragraph, and have paragraphs that proof or explain the point, there can be wide variety on where the thesis is expressed and the ancillary information presented that is supplemental to the thesis.  These are sometimes called essays.  However,  academic  essays do have a very specific organizational pattern.

Academic Essays

The introduction paragraph and the concluding paragraph of an essay are different from a general paragraph.  An introduction contains general background information on a topic and leads into a thesis statement.  The sentences with background information should be general and not contain proof of the thesis. The sentences should be relevant, however, and logically flow into the thesis.  Background sentences include information about the topic and the controversy. Some instructors may prefer other types of content in the introduction in addition to the thesis.  It is best to check with an instructor as to whether he or she has a preference for content.  In any case, there must be unity and coherence in an introduction paragraph as well. 

While the body paragraph of an academic is the same as a general paragraph in that they have a topic sentence and sentences that support it, the topic sentence must be a reason why the thesis of the essay is accurate.  Body paragraphs should clearly support the thesis and not contain any extraneous information. However, one way of proving your thesis is right is by presenting the opposing view and then rebutting it, that is, showing how it is not valid.  

Some instructors say that any opposing information should be in a separate rebuttal paragraph before the concluding paragraph.  If not specifically indicated by your instructor, either putting opposing information into the paragraphs related to the specific information or having a separate rebuttal paragraph is appropriate, but not both in the same essay.

A concluding paragraph sums up the proof and restates the thesis. Some instructors ask for a statement drawing an implication of the information presented instead of or in addition to a restatement of the thesis.  In either case, while a concluding paragraph as with the introduction paragraph does not start with a topic sentence and have the rest of the sentences support the topic sentence, the concluding paragraph is similar in that the summary of the proof ties directly into the thesis or statement of general implication.  There are not extraneous, off-topic sentences

Rhetorical Modes as Types of Paragraphs

Narration is when an author writes as though telling a story.  This mode is used more often in fiction, but it can be used in academic essay writing when the best way to help prove the thesis is by relating a sequence of events.

Description/Definition/Exemplification, and Classification

These closely related modes use specific information about certain aspects of a thing, event, or situation. The terms speak for themselves.  Description uses details describing the thing, event, or situation. Definition defines it. Exemplification uses examples, and classification uses categories.

The rose was red. (description)

A rose is a flower with soft petals and a beautiful, brief bloom. (definition)

Roses comes in a variety of colors such as red, yellow, and white. (example)

Roses come in a variety of types including miniature, climbing, hybrid tea, and floribunda. (classification)

Compare/Contrast

Comparing and/or contrasting one thing, event, or situation is a helpful way to show what it is and isn't.  If someone were arguing that a particular type of sneaker was the best, it would be useful to compare to others for support, durability, and price.

Cause and/or Effect

This mode is useful in arguing for or again an action.  Showing the cause and/or effect of an action can be persuasive.  For example, if someone were arguing for an increase in the speed limit, statistics showing an increase in fatalities where limits are higher would be a persuasive argument.

Persuasion/Argumentation

In a sense, the ultimate intent of all communication is persuasion.  Argumentation is one way of talking about debate.  We think of arguing as what we do among friends or family members - and it is - but there is a formal way to argue to prove our point.  Actually, we can learn how to better have civil arguments which will be constructive.  In thinking about persuasion/argumentation as a rhetorical mode, it refers to a type of writing that is clearly arguing in support of a specific point.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

How to Write an Essay Introduction (with Examples)   

The introduction of an essay plays a critical role in engaging the reader and providing contextual information about the topic. It sets the stage for the rest of the essay, establishes the tone and style, and motivates the reader to continue reading.

An introduction is the opening section of an essay, paper, or other written work. It introduces the topic and provides background information, context, and an overview of what the reader can expect from the rest of the work. 1 The key is to be concise and to the point, providing enough information to engage the reader without delving into excessive detail. 

The essay introduction is crucial as it sets the tone for the entire piece and provides the reader with a roadmap of what to expect. Here are key elements to include in your essay introduction: 

• Hook : Start with an attention-grabbing statement or question to engage the reader. This could be a surprising fact, a relevant quote, or a compelling anecdote. 
• Background information : Provide context and background information to help the reader understand the topic. This can include historical information, definitions of key terms, or an overview of the current state of affairs related to your topic. 
• Thesis statement : Clearly state your main argument or position on the topic. Your thesis should be concise and specific, providing a clear direction for your essay. 

Before we get into how to write an essay introduction, we need to know how it is structured. The structure of an essay is crucial for organizing your thoughts and presenting them clearly and logically. It is divided as follows: 2  

• Introduction:  The introduction should grab the reader’s attention with a hook, provide context, and include a thesis statement that presents the main argument or purpose of the essay.  
• Body:  The body should consist of focused paragraphs that support your thesis statement using evidence and analysis. Each paragraph should concentrate on a single central idea or argument and provide evidence, examples, or analysis to back it up.  
• Conclusion:  The conclusion should summarize the main points and restate the thesis differently. End with a final statement that leaves a lasting impression on the reader. Avoid new information or arguments. 

Here’s a step-by-step guide on how to write an essay introduction: 

• Start with a Hook : Begin your introduction paragraph with an attention-grabbing statement, question, quote, or anecdote related to your topic. The hook should pique the reader’s interest and encourage them to continue reading. 
• Provide Background Information : This helps the reader understand the relevance and importance of the topic. 
• State Your Thesis Statement : The last sentence is the main argument or point of your essay. It should be clear, concise, and directly address the topic of your essay. 
• Preview the Main Points : This gives the reader an idea of what to expect and how you will support your thesis. 
• Keep it Concise and Clear : Avoid going into too much detail or including information not directly relevant to your topic. 
• Revise : Revise your introduction after you’ve written the rest of your essay to ensure it aligns with your final argument. 

Here’s an example of an essay introduction paragraph about the importance of education: 

Education is often viewed as a fundamental human right and a key social and economic development driver. As Nelson Mandela once famously said, “Education is the most powerful weapon which you can use to change the world.” It is the key to unlocking a wide range of opportunities and benefits for individuals, societies, and nations. In today’s constantly evolving world, education has become even more critical. It has expanded beyond traditional classroom learning to include digital and remote learning, making education more accessible and convenient. This essay will delve into the importance of education in empowering individuals to achieve their dreams, improving societies by promoting social justice and equality, and driving economic growth by developing a skilled workforce and promoting innovation. 

This introduction paragraph example includes a hook (the quote by Nelson Mandela), provides some background information on education, and states the thesis statement (the importance of education). 

This is one of the key steps in how to write an essay introduction. Crafting a compelling hook is vital because it sets the tone for your entire essay and determines whether your readers will stay interested. A good hook draws the reader in and sets the stage for the rest of your essay.  

• Avoid Dry Fact : Instead of simply stating a bland fact, try to make it engaging and relevant to your topic. For example, if you’re writing about the benefits of exercise, you could start with a startling statistic like, “Did you know that regular exercise can increase your lifespan by up to seven years?” 
• Avoid Using a Dictionary Definition : While definitions can be informative, they’re not always the most captivating way to start an essay. Instead, try to use a quote, anecdote, or provocative question to pique the reader’s interest. For instance, if you’re writing about freedom, you could begin with a quote from a famous freedom fighter or philosopher. 
• Do Not Just State a Fact That the Reader Already Knows : This ties back to the first point—your hook should surprise or intrigue the reader. For Here’s an introduction paragraph example, if you’re writing about climate change, you could start with a thought-provoking statement like, “Despite overwhelming evidence, many people still refuse to believe in the reality of climate change.” 

Including background information in the introduction section of your essay is important to provide context and establish the relevance of your topic. When writing the background information, you can follow these steps: 

• Start with a General Statement:  Begin with a general statement about the topic and gradually narrow it down to your specific focus. For example, when discussing the impact of social media, you can begin by making a broad statement about social media and its widespread use in today’s society, as follows: “Social media has become an integral part of modern life, with billions of users worldwide.” 
• Define Key Terms : Define any key terms or concepts that may be unfamiliar to your readers but are essential for understanding your argument. 
• Provide Relevant Statistics:  Use statistics or facts to highlight the significance of the issue you’re discussing. For instance, “According to a report by Statista, the number of social media users is expected to reach 4.41 billion by 2025.” 
• Discuss the Evolution:  Mention previous research or studies that have been conducted on the topic, especially those that are relevant to your argument. Mention key milestones or developments that have shaped its current impact. You can also outline some of the major effects of social media. For example, you can briefly describe how social media has evolved, including positives such as increased connectivity and issues like cyberbullying and privacy concerns. 
• Transition to Your Thesis:  Use the background information to lead into your thesis statement, which should clearly state the main argument or purpose of your essay. For example, “Given its pervasive influence, it is crucial to examine the impact of social media on mental health.” 

A thesis statement is a concise summary of the main point or claim of an essay, research paper, or other type of academic writing. It appears near the end of the introduction. Here’s how to write a thesis statement: 

• Identify the topic:  Start by identifying the topic of your essay. For example, if your essay is about the importance of exercise for overall health, your topic is “exercise.” 
• State your position:  Next, state your position or claim about the topic. This is the main argument or point you want to make. For example, if you believe that regular exercise is crucial for maintaining good health, your position could be: “Regular exercise is essential for maintaining good health.” 
• Support your position:  Provide a brief overview of the reasons or evidence that support your position. These will be the main points of your essay. For example, if you’re writing an essay about the importance of exercise, you could mention the physical health benefits, mental health benefits, and the role of exercise in disease prevention. 
• Make it specific:  Ensure your thesis statement clearly states what you will discuss in your essay. For example, instead of saying, “Exercise is good for you,” you could say, “Regular exercise, including cardiovascular and strength training, can improve overall health and reduce the risk of chronic diseases.” 

Examples of essay introduction 

Here are examples of essay introductions for different types of essays: 

Argumentative Essay Introduction Example:  

Topic: Should the voting age be lowered to 16? 

“The question of whether the voting age should be lowered to 16 has sparked nationwide debate. While some argue that 16-year-olds lack the requisite maturity and knowledge to make informed decisions, others argue that doing so would imbue young people with agency and give them a voice in shaping their future.” 

Expository Essay Introduction Example  

Topic: The benefits of regular exercise 

“In today’s fast-paced world, the importance of regular exercise cannot be overstated. From improving physical health to boosting mental well-being, the benefits of exercise are numerous and far-reaching. This essay will examine the various advantages of regular exercise and provide tips on incorporating it into your daily routine.” 

Text: “To Kill a Mockingbird” by Harper Lee 

“Harper Lee’s novel, ‘To Kill a Mockingbird,’ is a timeless classic that explores themes of racism, injustice, and morality in the American South. Through the eyes of young Scout Finch, the reader is taken on a journey that challenges societal norms and forces characters to confront their prejudices. This essay will analyze the novel’s use of symbolism, character development, and narrative structure to uncover its deeper meaning and relevance to contemporary society.” 

• Engaging and Relevant First Sentence : The opening sentence captures the reader’s attention and relates directly to the topic. 
• Background Information : Enough background information is introduced to provide context for the thesis statement. 
• Definition of Important Terms : Key terms or concepts that might be unfamiliar to the audience or are central to the argument are defined. 
• Clear Thesis Statement : The thesis statement presents the main point or argument of the essay. 
• Relevance to Main Body : Everything in the introduction directly relates to and sets up the discussion in the main body of the essay. 

Writing a strong introduction is crucial for setting the tone and context of your essay. Here are the key takeaways for how to write essay introduction: 3  

• Hook the Reader : Start with an engaging hook to grab the reader’s attention. This could be a compelling question, a surprising fact, a relevant quote, or an anecdote. 
• Provide Background : Give a brief overview of the topic, setting the context and stage for the discussion. 
• Thesis Statement : State your thesis, which is the main argument or point of your essay. It should be concise, clear, and specific. 
• Preview the Structure : Outline the main points or arguments to help the reader understand the organization of your essay. 
• Keep it Concise : Avoid including unnecessary details or information not directly related to your thesis. 
• Revise and Edit : Revise your introduction to ensure clarity, coherence, and relevance. Check for grammar and spelling errors. 
• Seek Feedback : Get feedback from peers or instructors to improve your introduction further. 

The purpose of an essay introduction is to give an overview of the topic, context, and main ideas of the essay. It is meant to engage the reader, establish the tone for the rest of the essay, and introduce the thesis statement or central argument.  

An essay introduction typically ranges from 5-10% of the total word count. For example, in a 1,000-word essay, the introduction would be roughly 50-100 words. However, the length can vary depending on the complexity of the topic and the overall length of the essay.

An essay introduction is critical in engaging the reader and providing contextual information about the topic. To ensure its effectiveness, consider incorporating these key elements: a compelling hook, background information, a clear thesis statement, an outline of the essay’s scope, a smooth transition to the body, and optional signposting sentences.  

The process of writing an essay introduction is not necessarily straightforward, but there are several strategies that can be employed to achieve this end. When experiencing difficulty initiating the process, consider the following techniques: begin with an anecdote, a quotation, an image, a question, or a startling fact to pique the reader’s interest. It may also be helpful to consider the five W’s of journalism: who, what, when, where, why, and how.   For instance, an anecdotal opening could be structured as follows: “As I ascended the stage, momentarily blinded by the intense lights, I could sense the weight of a hundred eyes upon me, anticipating my next move. The topic of discussion was climate change, a subject I was passionate about, and it was my first public speaking event. Little did I know , that pivotal moment would not only alter my perspective but also chart my life’s course.” 

Crafting a compelling thesis statement for your introduction paragraph is crucial to grab your reader’s attention. To achieve this, avoid using overused phrases such as “In this paper, I will write about” or “I will focus on” as they lack originality. Instead, strive to engage your reader by substantiating your stance or proposition with a “so what” clause. While writing your thesis statement, aim to be precise, succinct, and clear in conveying your main argument.  

To create an effective essay introduction, ensure it is clear, engaging, relevant, and contains a concise thesis statement. It should transition smoothly into the essay and be long enough to cover necessary points but not become overwhelming. Seek feedback from peers or instructors to assess its effectiveness.

Once you decide on a method for organizing your essay, you’ll want to start drafting your paragraphs. Think of your paragraphs as links in a chain where coherence and continuity are key. Imagine reading one long block of text, with each idea blurring into the next. You are likely to lose interest in a piece of writing that is disorganized and spans many pages without breaks. Paragraphs separate ideas into logical, manageable chunks, each paragraph focusing on only one main idea and presenting coherent sentences to support that one point. Because all the sentences in one paragraph support the same point, a paragraph may stand on its own. For most types of informative or persuasive academic writing, writers find it helpful to think of the paragraph analogous to an essay, as each is controlled by a main idea or point, and that idea is developed by an organized group of more specific ideas. Thus, the thesis of the essay is analogous to the topic sentence of a paragraph, just as the supporting sentences in a paragraph are analogous to the supporting paragraphs in an essay.

In essays, each supporting paragraph adds another related main idea to support the writer’s thesis, or controlling idea. Each related supporting idea is developed with facts, examples, and other details that explain it. By exploring and refining one idea at a time, writers build a strong case for their thesis. Effective paragraphing makes the difference between a satisfying essay that readers can easily process and one that requires readers to mentally organize the piece themselves. Thoughtful organization and development of each body paragraph leads to an effectively focused, developed, and coherent essay.

An effective paragraph contains three main parts:

• a topic sentence
• body, supporting sentences
• a concluding sentence

In informative and persuasive writing, the topic sentence is usually the first or second sentence of a paragraph and expresses its main idea, followed by supporting sentences that help explain, prove, or enhance the topic sentence. In narrative and descriptive paragraphs, however, topic sentences may be implied rather than explicitly stated, with all supporting sentences working to create the main idea. If the paragraph contains a concluding sentence, it is the last sentence in the paragraph and reminds the reader of the main point by restating it in different words.

Creating Focused Paragraphs with Topic Sentences

The foundation of a paragraph is the topic sentence which expresses the main idea or point of the paragraph. A topic sentence functions in two ways: it clearly refers to and supports the essay’s thesis, and it indicates what will follow in the rest of the paragraph. As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information such as facts, details, or examples.

An effective topic sentence has the following characteristics:

• A topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak Example

First, we need a better way to educate students.

Explanation: The claim is vague because it does not provide enough information about what will follow and it is too broad to be covered effectively in one paragraph.

Stronger Example

Creating a national set of standards for math and English education will improve student learning in many states.

Explanation: The sentence replaces the vague phrase “a better way” and leads readers to expect supporting facts and examples as to why standardizing education in these subjects might improve student learning in many states.

• A good topic sentence is the most general sentence in the paragraph and thus does not include supporting details.

Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the same team to win year after year.

Explanation: This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.

Introducing a salary cap would improve the game of baseball for many reasons.

Explanation: This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph, yet the sentence still makes a claim about salary caps – improvement of the game.

• A good topic sentence is clear and easy to follow.

In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types.

Explanation: The confusing sentence structure and unnecessary vocabulary bury the main idea, making it difficult for the reader to follow the topic sentence.

Most forms of writing can be improved by first creating an outline.

Explanation: This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow. The writer can include examples of what kinds of writing can benefit from outlining in the supporting sentences.

Location of Topic Sentences

As previously discussed, a topic sentence can appear anywhere within a paragraph depending upon the mode of writing, or it can be implied such as in narrative or descriptive writing. In college-level expository or persuasive writing, placing an explicit topic sentence at the beginning of each paragraph (the first or second sentence) makes it easier for readers to follow the essay and for writers to stay on topic, but writers should be aware of variations and maintain the flexibility to adapt to different writing projects. The following examples illustrate varying locations for the topic sentence. In each example, the topic sentence is underlined.

Topic Sentence Begins the Paragraph (General to Specific)

After reading the new TV guide this week I wondered why we are still being bombarded with reality shows, a plague that continues to darken our airwaves. Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. Prisoner follows the daily lives of eight suburban housewives who have chosen to be put in jail for the purposes of this fake psychological experiment. A preview for the first episode shows the usual tears and tantrums associated with reality television. I dread to think what producers will come up with next season and hope that other viewers will express their criticism. These producers must stop the constant stream of meaningless shows without plotlines. We’ve had enough reality television to last us a lifetime.

The first sentence tells readers that the paragraph will be about reality television shows, and it expresses the writer’s distaste for these shows through the use of the word bombarded . Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show and why the writer finds it unappealing. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show Prisoner ). Most academic essays contain the topic sentence at the beginning of the first paragraph. However, when utilizing a specific to general method, the topic sentence may be located later in the paragraph.

Topic Sentence Ends the Paragraph (Specific to General)

Last year, a cat traveled 130 miles to reach its family who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals’ senses are better than humans’). In this case, the supporting sentences are placed before the topic sentence, and the concluding sentence is the same as the topic sentence. This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

When the Topic Sentence Appears in the Middle of the Paragraph

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety—breathing exercises. It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It’s amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the underlined sentence is the topic sentence. It expresses the main idea—that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety. Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic.

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all, a technique often used in descriptive and narrative writing. Instead of being directly stated, the main idea is implied in the content of the paragraph, as in the following narrative paragraph.

Example of Implied Topic Sentence

Heaving herself up the stairs, Luella had to pause for breath several times. She let out a wheeze as she sat down heavily in the wooden rocking chair. Tao approached her cautiously, as if she might crumble at the slightest touch. He studied her face, like parchment, stretched across the bones so finely he could almost see right through the skin to the decaying muscle underneath. Luella smiled a toothless grin.

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept—that Luella is extremely old. The topic sentence is thus implied rather than stated so that all the details in the paragraph can work together to convey the dominant impression of Luella’s age. In a paragraph such as this one, an explicit topic sentence would seem awkward and heavy-handed. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.

Developing Paragraphs

If you think of a paragraph as a sandwich, the supporting sentences are the filling between the bread. They make up the body of the paragraph by explaining, proving, or enhancing the controlling idea in the topic sentence. The overall method of development for paragraphs depends upon the essay as a whole and the purpose of each paragraph; thus paragraphs may be developed by using examples, description, narration, comparison and contrast, definition, cause and effect, classification and division. A writer may use one method or combine several methods.

Writers often want to know how many words a paragraph should contain, and the answer is that a paragraph should develop the idea, point, or impression completely enough to satisfy the writer and readers. Depending on their function, paragraphs can vary in length from one or two sentences, to over a page; however, in most college assignments, successfully developed paragraphs usually contain approximately one hundred to two hundred and fifty words and span one-fourth to two-thirds of a typed page. A series of short paragraphs in an academic essay can seem choppy and unfocused, whereas paragraphs that are one page or longer can tire readers. Giving readers a paragraph break on each page helps them maintain focus.

This advice does not mean, of course, that composing a paragraph of a particular number of words or sentences guarantees an effective paragraph. Writers must provide enough supporting sentences within paragraphs to develop the topic sentence and simultaneously carry forward the essay’s main idea.

For example, in a descriptive paragraph about a room in the writer’s childhood home, a length of two or three sentences is unlikely to contain enough details to create a picture of the room in the reader’s mind, and it will not contribute in conveying the meaning of the place. In contrast, a half page paragraph, full of carefully selected vivid, specific details and comparisons, provides a fuller impression and engages the reader’s interest and imagination. In descriptive or narrative paragraphs, supporting sentences present details and actions in vivid, specific language in objective or subjective ways, appealing to the readers’ senses to make them see and experience the subject. In addition, some sentences writers use make comparisons that bring together or substitute the familiar with the unfamiliar, thus enhancing and adding depth to the description of the incident, place, person, or idea.

In a persuasive essay about raising the wage for certified nursing assistants, a paragraph might focus on the expectations and duties of the job, comparing them to that of a registered nurse. Needless to say, a few sentences that simply list the certified nurse’s duties will not give readers a complete enough idea of what these healthcare professionals do. If readers do not have plenty of information about the duties and the writer’s experience in performing them for what she considers inadequate pay, the paragraph fails to do its part in convincing readers that the pay is inadequate and should be increased.

In informative or persuasive writing, a supporting sentence usually offers one of the following:

• Reason: The refusal of the baby boom generation to retire is contributing to the current lack of available jobs.
• Fact: Many families now rely on older relatives to support them financially.
• Statistic: Nearly 10 percent of adults are currently unemployed in the United States.
• Quotation: “We will not allow this situation to continue,” stated Senator Johns.
• Example: Last year, Bill was asked to retire at the age of fifty-five.

The type of supporting sentence you choose will depend on what you are writing and why you are writing. For example, if you are attempting to persuade your audience to take a particular position, you should rely on facts, statistics, and concrete examples, rather than personal opinions. Personal testimony in the form of an extended example can be used in conjunction with the other types of support.

Consider the elements in the following paragraph.

Example Persuasive Paragraph

Topic sentence: There are numerous advantages to owning a hybrid car.

Sentence 1 (statistic): First, they get 20 percent to 35 percent more miles to the gallon than a fuel- efficient gas-powered vehicle.

Sentence 2 (fact): Second, they produce very few emissions during low speed city driving.

Sentence 3 (reason): Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump.

Sentence 4 (example): Alex bought a hybrid car two years ago and has been extremely impressed with its performance.

Sentence 5 (quotation): “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas powered vehicles I’ve owned.”

Concluding sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Sometimes the writing situation does not allow for research to add specific facts or other supporting information, but paragraphs can be developed easily with examples from the writer’s own experience.

Farheya, a student in a freshman English Composition class, quickly drafted an essay during a timed writing assignment in class. To practice improving paragraph development, she selected the body paragraph below to add support:

Example of Original Body Paragraph

Topic: Would you be better off if you didn’t own a television? Discuss.

Lack of ownership of a television set is also a way to preserve innocence, and keep the exposure towards anything inappropriate at bay. From simply watching a movie, I have seen things I shouldn’t have, no matter how fast I switch the channel. Television shows not only display physical indecency, but also verbal. Many times movies do voice-overs of profane words, but they also leave a few words uncensored. Seeing how all ages can flip through and see or hear such things make t.v. toxic for the mind, and without it I wouldn’t have to worry about what I may accidentally see or hear.

The original paragraph identifies two categories of indecent material, and there is mention of profanity to provide a clue as to what the student thinks is indecent. However, the paragraph could use some examples to make the idea of inappropriate material clearer. Farheya considered some of the television shows she had seen and made a few changes.

Example of Revised Body Paragraph

Not owning a television set would also be a way to preserve innocence and keep my exposure to anything inappropriate at bay. While searching for a program to view, I have seen things I shouldn’t have, no matter how fast I switched the channel. The synopsis of Euro Trip, which describes high school friends traveling across Europe, leads viewers to think that the film is an innocent adventure; however; it is filled with indecency, especially when the students reach Amsterdam. The movie Fast and Furious has the same problem since the women are all half-naked in half tops and mini-skirts or short- shorts. Television shows not only display physical indecency, but also verbal. Many television shows have no filters, and the characters say profane words freely. On Empire, the main characters Cookie and Lucious Lyon use profane words during their fights throughout entire episodes. Because The Big Bang Theory is a show about a group of science geeks and their cute neighbor, viewers might think that these science geniuses’ conversations would be about their current research or other science topics. Instead, their characters regularly engage in conversations about their personal lives that should be kept private. The ease of flipping through channels and seeing or hearing such things makes t.v. toxic for the mind, and without a television I wouldn’t have to worry about what I may accidentally see or hear.

Farheya’s addition of a few examples helps to convey why she thinks she would be better off without a television.

Concluding Sentences

An effective concluding sentence draws together all the ideas raised in your paragraph. It reminds readers of the main point—the topic sentence—without restating it in exactly the same words. Using the hamburger example, the top bun (the topic sentence) and the bottom bun (the concluding sentence) are very similar. They frame the “meat” or body of the paragraph.

Compare the topic sentence and concluding sentence from the first example on hybrid cars:

Topic Sentence: There are many advantages to owning a hybrid car.

Concluding Sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Notice the use of the synonyms advantages and benefits . The concluding sentence reiterates the idea that owning a hybrid is advantageous without using the exact same words. It also summarizes two examples of the advantages covered in the supporting sentences: low running costs and environmental benefits.

Writers should avoid introducing any new ideas into a concluding sentence because a conclusion is intended to provide the reader with a sense of completion. Introducing a subject that is not covered in the paragraph will confuse readers and weaken the writing.

A concluding sentence may do any of the following:

• Restate the main idea.

Childhood obesity is a growing problem in the United States.

• Summarize the key points in the paragraph

A lack of healthy choices, poor parenting, and an addiction to video games are among the many factors contributing to childhood obesity.

• Draw a conclusion based on the information in the paragraph.

These statistics indicate that unless we take action, childhood obesity rates will continue to rise.

• Make a prediction, suggestion, or recommendation about the information in the paragraph.

Based on this research, more than 60 percent of children in the United States will be morbidly obese by the year 2030 unless we take evasive action.

• Offer an additional observation about the controlling idea.

Childhood obesity is an entirely preventable tragedy.

Paragraph Length

Although paragraph length is discussed in the section on developing paragraphs with supporting sentences, some additional reminders about when to start a new paragraph may prove helpful to writers:

• If a paragraph is over a page long, consider providing a paragraph break for readers. Look for a logical place to divide the paragraph; then revise the opening sentence of the second paragraph to maintain coherence.
• A series of short paragraphs can be confusing and choppy. Examine the content of the paragraphs and combine ones with related ideas or develop each one further.
• When dialogue is used, begin a new paragraph each time the speaker changes.
• Begin a new paragraph to indicate a shift in subject, tone, or time and place.

Improving Paragraph Coherence

A strong paragraph holds together well, flowing seamlessly from the topic sentence into the supporting sentences and on to the concluding sentence. To help organize a paragraph and ensure that ideas logically connect to one another, writers use a combination of elements:

• A clear organizational pattern: chronological (for narrative writing and describing processes), spatial (for descriptions of people or places), order of importance, general to specific (deductive), specific to general (inductive)
• Transitional words and phrases: These connecting words describe a relationship between ideas.
• Repetition of ideas: This element helps keep the parts of the paragraph together by maintaining focus on the main idea, so this element reinforces both paragraph coherence and unity.

In the following example, notice the use of transitions ( bolded ) and key words ( underlined ):

Example of Transition Words

Owning a hybrid car benefits both the owner and the environment . First , these cars get 20 percent to 35 percent more miles to the gallon than a fuel-efficient gas-powered vehicle. Second , they produce very few emissions during low speed city driving. Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump. Alex bought a hybrid car two years ago and has been extremely impressed with its performance. “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas-powered vehicles I’ve owned.” Given the low running costs and environmental benefits of owning a hybrid car , it is likely that many more people will follow Alex’s example in the near future.

Words such as first and second are transition words that show sequence or clarify order. They help organize the writer’s ideas by showing that he or she has another point to make in support of the topic sentence. The transition word because is a transition word of consequence that continues a line of thought. It indicates that the writer will provide an explanation of a result. In this sentence, the writer explains why hybrid cars will reduce dependency on fossil fuels (because they do not require gas).

In addition to transition words, the writer repeats the word hybrid (and other references such as these cars , and they ), and ideas related to benefits to keep the paragraph focused on the topic and hold it together.

To include a summarizing transition for the concluding sentence, the writer could rewrite the final sentence as follows:

In conclusion, given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Although the phrase “in conclusion” certainly reinforces the idea of summary and closure, it is not necessary in this case and seems redundant, as the sentence without the phrase already repeats and summarizes the benefits presented in the topic sentence and flows smoothly from the preceding quotation. The second half of the sentence, in making a prediction about the future, signals a conclusion, also making the phrase “in conclusion” unnecessary. The original version of the concluding sentence also illustrates how varying sentence openings can improve paragraph coherence. As writers continue to practice and develop their style, they more easily make these decisions between using standard transitional phrases and combining the repetition of key ideas with varied sentence openings.

Table 5.3.1 provides some useful transition words and phrases to connect sentences within paragraphs as well as to connect body paragraphs:

How teachers can tell if a student has used ChatGPT in an essay

Experts have revealed the tell-tale signs that an essay has been written by ChatGPT and not a student.

It comes after the rise of generative AI tools, like ChatGPT, has sparked concerns about cheating among pupils in the education sector.

Repetition of words, tautology and paragraphs starting with “however” are some tell-tale features, researchers said.

The writing style of the artificial intelligence tool is “bland” and “journalistic”, according to a Cambridge University Press and Assessment study.

Researchers compared essays written by three first-year undergraduate students, with the aid of ChatGPT, with 164 essays written by IGCSE students.

These essays were marked by examiners and the undergraduates were then interviewed and their essays were analysed.

The study found essays written with the help of ChatGPT performed poorly on analysis and comparison skills compared to non-ChatGPT-assisted essays.

But ChatGPT-assisted essays performed strongly on information and reflection skills.

Researchers identified a number of key features of the ChatGPT writing style, which included the use of Latinate vocabulary, repetition of words or phrases and ideas, and pleonasms.

Essays written with the help of ChatGPT were also more likely to use paragraphs starting with discourse markers like “however”, “moreover”, and “overall”, and numbered lists with items.

The researchers said ChatGPT’s default writing style “echoes the bland, clipped, and objective style that characterises much generic journalistic writing found on the internet”.

The report said: “The students found ChatGPT useful for gathering information quickly.

“However, they considered that complete reliance on this technology would produce essays of a low academic standard.”

Lead researcher Jude Brady, of Cambridge University Press and Assessment, said: “Our findings offer insights into the growing area of generative AI and assessment, which is still largely uncharted territory.

“Despite the small sample size, we are excited about these findings as they have the capacity to inform the work of teachers as well as students.”

She added: “We hope our research might help people to identify when a piece of text has been written by ChatGPT.

“For students and the wider population, learning to use and detect generative AI forms an increasingly important aspect of digital literacy.”
