What is an expository essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

The structure of the expository essay is held together by the following.

• A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

• Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse.

• Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph.

• Evidential support (whether factual, logical, statistical, or anecdotal).

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

• A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

• A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students will inevitably begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize and come to a conclusion concerning the information presented in the body of the essay.

A complete argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of the Great Depression and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The five-paragraph Essay

A common method for writing an expository essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of:

• an introductory paragraph
• three evidentiary body paragraphs
• a conclusion

How to Write an Expository Essay

Every student has to write an expository essay at least once in their educational career. These are actually fairly simple essays to write, but they do require some serious research skills. Like most academic essays, the expository essay requires formal writing with an introduction, body, and conclusion.

Guide Overview

• Focus on the thesis
• Listen to the assignment
• Explain, don’t argue
• Revise and edit, revise and edit
• Choosing the right topic

Tips for Writing a Kick-Butt Essay

Want to really impress your professor? Here are a few ways you can turn an ordinary essay into something that will blow their socks off.

Focus on the Thesis

Your thesis is the central point of the entire essay, so if it’s amazing, you’re off to a great start. Begin with this and make sure you decide on something that is impressive to kick off the essay.

Listen to the Assignment

Your professor may give you hints on what they’re looking for. If you just write down the basics of the assignment, you could miss out on some key points. For example, your professor may hint at a preferred topic or give tips that could result in a higher score. Write it all down and then analyze what is wanted before you write.

Long before you actually put pen to paper or fingers to keyboard to write the essay, you need to complete the pre-writing phase. This is where you do research and outline your essay. You’ll be amazed at how much better your writing is when you have these basic elements in place first. If you need help with these basic elements consider using an Expository Essay Template.

Explain, Don’t Argue

If you’re not careful, an expository essay can turn into a persuasive or argumentative essay. Focus on explaining the topic, rather than convincing people of something about it.

Revise and Edit, Revise and Edit

Going over the essay once to edit and polish isn’t really enough. If you’re tight on time, such as when writing an essay for an exam, just once will do. However, if you have time, it’s a good idea to edit immediately, then let the essay sit overnight or even longer. When you come back, you won’t be as close to the writing and can look at it more objectively.

Choosing the Right Topic

Topics for an expository essay vary widely, but ideally, you should select something you’re interested in writing about. Topics can answer a question such as “How can we prevent bullying in school?” or they can describe something like a historical building in your area. Other interesting topics to inspire you include:

• How does technology affect our relationships?
• How to treat a burn
• What are the must-haves for a freshman in college?
• How to handle anxiety attacks naturally
• How to train your dog to stop barking on command
• Research the history of a monument in your area
• Why roller skating is a great exercise

As you can see, there’s no limit to the types of topics you can choose for your essay and it really comes down to what the professor assigns you and what you enjoy writing about. How narrow your topic is will also depend on how much you plan to write. An entire history of the Civil War won’t fit into two page, for example, so you’ll need to narrow it down to a specific battle or element of the Civil War.

Writing an expository essay can actually be a fun experience if you approach it the right way. When you enjoy the topic and are interested in it, your essay will show that and will stand out from those written out of boredom.

Finally, if you’re ever facing writer’s block for your college paper, consider WriteWell Essay Templates to help you get started.

How to Write an Expository Essay

Published by Grace Graffin at August 17th, 2021 , Revised On July 26, 2023

Expository means “to describe or explain something” . It is related to the words ‘exposition’, ‘expound’, and ‘expose’ – to explain or reveal the meaning, to lay open, speak one’s mind.

Whenever there is a need to gather research and describe an idea, a  topic , or a process clearly and logically, it is done in the form of an expository  essay .

An expository essay requires the writer to take a balanced approach to the subject matter rather than justifying a particular point of view.

Expository essays are assigned to students to evaluate their subject knowledge and composition skills. When compared with  argumentative essays , they involve a lot less research.

Definition of Expository Essay

“The expository essay is the  type of essay  that involves an investigation of an idea or topic, appraises relevant supporting evidence material, and presents an argument in a clear and concise manner. ”

When to Write an Expository Essay

Your school or university could assign an expository essay to you as coursework or as part of an online exam.

However, the guidelines may or may not clearly state that your assignment is an expository essay. If that is the case, then look for keywords like ‘explain’, ‘describe’, ‘define’, etc., to be sure that what has been asked for is an expository essay.

You might even be asked to explain and emphasise a particular concept or term. Writing a simple definition will not be enough because you will be expected to explore the ideas in detail.

Writing an Expository Essay

An expository essay should not be based on your  personal  experiences and opinions. It rather takes an objective approach. You will be expected to explain the topic in a balanced way without any personal bias.

Make sure to avoid the first and second person (“I” and “You”) when writing an expository essay.

How to Structure an Expository Essay

The  structure  and format of your expository essay assignment will depend on your school’s guidelines and the topic you are investigating. However, it is always a good idea to develop an outline for your  essay  before starting to work.

The Five-Paragraph Essay Writing Approach

An expository essay will require you to take the five-paragraph essay approach: an  introductory paragraph , a main body paragraph , and a concluding paragraph . This is often referred to as the hamburger style of the essay because, like a hamburger, it contains five main parts: the introduction and conclusion being the bun that encapsulates everything.

Rationale and Thesis Statement

Start your essay  with a rationale and thesis, also known as the  thesis statement , so your readers know what you set out to achieve in your expository essay assignment. Ensure the thesis statement is narrow enough to follow the guidelines in the assignment brief. If the thesis statement is weak and too broad, you will struggle to produce a flawless expository essay.

The Framework

Construct a framework, so you know what elements will constitute the basis of your essay.

Expository Essay Introduction

Like other  essay types , an expository essay begins with an  introduction , including a hook, background to the topic, and a thesis statement. Once you have grabbed the readers’ interest, it will be easier to get them to read the remaining essay.

Frequently Asked Questions

Will i need the skill of expository writing after i finish my studies.

It depends on what you are studying for. While you might or might not write any more expository essays after your formal education has ended, the skill will be very useful in certain careers, such as business reports, journalism, and in scientific and technical writing.

How does an expository essay differ from an argumentative essay?

An argumentative essay is usually longer and requires more research. It starts with a claim about something that will need supporting evidence. And both sides of the argument need to be discussed. In an expository essay, there is no requirement to make an original argument and defend/support it.

What is the purpose of expository essays?

This style of essay is necessary when you have to showcase your knowledge on a given subject, or your ability to gather research on one and present your findings.

How long is an expository essay?

There is no fixed length but an expository essay could be part of an exam, in which case it might only be 1,000 words or less. They are usually shorter than argumentative essays . It can depend on the subject under discussion. You will likely be given instructions on the required word count.

Are there different types of expository essay?

There are six different types of expository essay, each with a different purpose.

The six types are:

Process essay – describing a task, a method, how to complete something Cause and effect essay – why something happened and its effects Problem-solution essay – provide analysis of problems and their solutions Compare and contrast essay – describe the similarities and differences between two subjects Definition essay – define the topic in detail and explain the how, what, and why Classification essay – separate the topic’s categories and define them in detail

When you are assigned your essay, you should be able to distinguish which of these approaches you are required to take.
