What Is a Thesis Statement?

Table of Contents

A thesis statement is a concise summary of the main point or claim of an essay, research paper, or other piece of academic writing.

It presents the topic of your paper and your position on the topic, ideally in a single sentence.

Think of it as the roadmap to your paper—it guides your readers through your arguments and provides a clear direction.

Key Elements of a Thesis Statement

• Clarity: Your thesis should be clear and specific.
• Position: It should convey your stance on the topic.
• Argument: The statement should make a claim that others might dispute.

Types of Thesis Statements

There are various types of thesis statements depending on the kind of paper you’re writing.

Here are the main ones:

• Standard Method – This is the classic thesis statement used in many academic essays. It provides a straightforward approach, clearly stating the main argument or claim and outlining the supporting points.
• Research Paper – Designed for research papers, this type involves extensive research and evidence. It presents a hypothesis or a central argument based on your research findings.
• Informative Essay – Used for essays that aim to inform or explain a topic. It provides a clear summary of what the reader will learn.
• Persuasive Essay – For essays meant to persuade or convince the reader of a particular point of view. It clearly states your position and outlines your main arguments.
• Compare and Contrast Essay – Used when comparing two or more subjects. It highlights the similarities and differences between the subjects and presents a clear argument based on these comparisons.
• Analytical Essay – Breaks down an issue or idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
• Argumentative Essay – Makes a claim about a topic and justifies this claim with specific evidence. It’s similar to the persuasive essay but usually requires more evidence and a more formal tone.
• Expository Essay – Explains or describes a topic in a straightforward, logical manner. It provides a balanced analysis of a subject based on facts without opinions.
• Narrative Essay – Tells a story or relates an event. The thesis statement for a narrative essay usually highlights the main point or lesson of the story.
• Cause and Effect Essay – Explores the causes of a particular event or situation and its effects. It provides a clear argument about the cause and effect relationship.

How to Write a Thesis Statement (Standard Method)

Writing a standard thesis statement involves a few straightforward steps.

Here’s a detailed guide:

• Identify Your Topic: What is your essay about?

Thesis Statement Tips

Writing a strong thesis statement is crucial for a successful essay. Here are some tips to help you craft a killer thesis statement:

• Be Specific: Avoid vague language. Make sure your thesis statement clearly defines your argument or main point.
• Be Concise: Keep it to one or two sentences. Your thesis statement should be brief and to the point.
• Make It Arguable: Ensure that your thesis statement presents a claim or argument that can be disputed.
• Place It Appropriately: Typically, your thesis statement should be placed at the end of your introduction paragraph.
• Revise and Refine: Don’t be afraid to revise your thesis statement as you write and refine your essay. It should evolve as your ideas develop.

Common Thesis Statement Errors

Avoid these common errors when crafting your thesis statement:

• Too Broad: A thesis statement that is too broad makes it difficult to focus your essay. Narrow it down to a specific point.
• Too Vague: Avoid vague language that lacks specificity. Be clear about what you’re arguing.
• Lacks an Argument: Ensure that your thesis statement makes a clear argument or claim. Avoid statements that are purely factual or descriptive.
• Too Complex: A thesis statement should be straightforward and easy to understand. Avoid overly complex sentences.
• Off-Topic: Make sure your thesis statement is directly related to the topic of your essay. Stay on track.

How Do You Start a Thesis Statement?

Starting a thesis statement involves using clear and concise language that sets the stage for your argument.

Here are some exact words and phrases to begin with:

• “The purpose of this paper is to…”
• “This essay will argue that…”
• “In this essay, I will demonstrate that…”
• “The central idea of this paper is…”
• “This research aims to prove that…”
• “This study focuses on…”
• “This analysis will show that…”
• “The main argument presented in this paper is…”
• “The goal of this essay is to…”
• “Through this research, it will be shown that…”

How Long Should a Thesis Statement Be?

A thesis statement should be clear and concise, typically one to two sentences long.

Aim for 20 to 30 words, ensuring it includes the main topic, your position, and the key points that will be covered in your paper.

This provides a focused and precise summary of your argument, making it easier for readers to understand the main direction of your essay or research paper.

While brevity is essential, it’s also crucial to provide enough detail to convey the scope of your argument.

Avoid overly complex sentences that can confuse readers. Instead, strive for a balance between clarity and comprehensiveness, ensuring your thesis statement is straightforward and informative.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.
