A strong thesis statement is the lynchpin of all great essays.

Why? One of the things that gets drilled into you when learning how to write academic or expository essays is that thesis statements are important for several reasons: first off, the thesis statement tells what your essay is about—which is a good thing for everyone. (No cliffhangers)! Serious readers want to know what the subject is before they engage with new content. You don’t walk into a movie without having some idea of what it’s about, do you?

Second, the thesis statement presents a position. It tells what, or why, or how. It shows the reader right off the bat that you know what you’re talking about.

In other words, the thesis statement is where you earn the reader’s trust.

In this article, we are going to help you better understand the art of writing a good thesis statement. You will learn why thesis statements are so important in academic writing, and how to improve your own thesis statements.

What Is a Thesis Statement?


A thesis statement is a single sentence that tells the main idea, point, argument or purpose of an essay. Its primary role is to guide the writer’s ideas and provide a roadmap for the reader. A strong thesis statement is clear, concise, and specific, setting the stage for a well-structured essay.


Depending on the type of essay you are writing, your thesis statement could take on many different forms. The form of the thesis statement matches the purpose of your essay. If you are writing an argumentative essay, your thesis statement would be argumentative. A descriptive essay might have a more informative thesis statement. Some thesis statements outline several core components of your essay, and others summarize the main points you will make.


Regardless of its type, ultimately your thesis statement should be as punchy as possible. You want to make your reader genuinely interested in what you have to say, which means writing a thesis statement that is interesting and specific. It should be brief, to the point, clear, concise, and coherent.

Types of Thesis Statement

Just as there are different types of essays, there are also different types of thesis statements. The main types you are likely to write include the analytical thesis statement, the expository or explanatory thesis statement, and the argumentative thesis statement.

  • Analytical Thesis Statement: This type breaks down an idea or issue into its components, evaluates the issue, and presents this breakdown and evaluation to the audience. For example, “The increase in greenhouse gases is leading to climate change due to the industrial revolution, deforestation, and extensive use of fossil fuels.”
  • Expository Thesis Statement: This explains something to the audience. For example, “The process of photosynthesis is essential for plant life as it converts light energy into chemical energy.”
  • Argumentative Thesis Statement: This makes a claim that others might dispute. For example, “School uniforms should be mandatory in all schools because they reduce peer pressure, enhance discipline, and create a sense of community.”

How to Write a Strong Thesis Statement

Here are the main steps in writing a good thesis statement:

  • Background Research and Brainstorming
  • Outlining
  • Take the Plunge!
  • Revising

Step I: Background Research

It might surprise you to learn that the first step in writing a good thesis statement has nothing at all to do with writing! Before you even begin writing, you need to know what you are going to say, and the only way to know what to say in the essay is to do some background research on the topic.

If you are not writing a research essay, then brainstorming serves the same purpose as research. For example, a narrative or descriptive essay does not necessarily require formal research, but it might require you to reflect on your personal experiences. Reflecting on your personal experiences can be considered a type of “research,” in that you are digging deep and examining as much information or detail as possible.

Step II: Outlining

You will now take what you have learned in your research or brainstorming session and begin to outline your essay. An outline helps you organize your thoughts and plan your essay. Just as you cannot build a house properly without a blueprint, you cannot write an essay properly without an outline. You might be able to outline your thoughts in your head, but some students find that a written outline helps them stay focused. Once you outline your main ideas, you will realize that your thesis statement practically writes itself!

Step III: Take the Plunge!

Do not be afraid of writing your thesis statement. Now that you pretty much know what you are going to say, or what you want to prove, in your essay, just write a thesis statement using the handy tips we are offering you here in this article.

Step IV: Revising

You will often find you need to revise your thesis statement. Perhaps you found that your original ideas lacked substantive evidence to support them, or perhaps you realized that your claim was too weak. Regardless of the reason, never be afraid to change your mind.

To Recap:

  1. Choose a Topic: Select a relevant and manageable topic that interests you. Tips: Go after something you know a lot about, wouldn’t mind researching more, or have a real love for. It will be much harder to write well if you don’t care about the subject.
  2. Formulate the Statement: Start with a question about your topic, and then answer it with your thesis statement. Make sure it is clear and focused by revising it again and again.
  3. Examples of Strong vs. Weak Thesis Statements: A weak thesis might be, “Many people consume fast food.” A strong thesis would be, “Consuming fast food regularly leads to severe health issues such as obesity, diabetes, and heart disease.”

Thesis Statements for Types of Essays

Compare/Contrast Essays

Weak: London and Paris are totally different cities.

Strong: London and Paris are both major world capitals, but differ in terms of lifestyle, history, language, and culture.

Explanation: The weak thesis statement lacks specificity and clarity. Everyone knows London and Paris are totally different cities, but why are they different? The second, stronger thesis statement indicates that you are going to compare the two capitals on the basis of lifestyle, history, language, and culture.

Weak: Both Hamlet and Oedipus are tragic figures, with similar tragic flaws related to their blindness to the truth, which is why their hubris gets them into trouble.

Strong: Tragic heroes Hamlet and Oedipus both have good intentions as leaders, but their pride and stubbornness lead to their devastating demise.

Explanation: Notice how the weaker of these statements is incoherent and cluttered. The second statement shows how you intend to compare and contrast Hamlet and Oedipus.

Argumentative Essays

Weak: Obamacare is a failure because Americans cannot deal with socialism.

Strong: The individual mandate aspect of the ACA presented legal problems, which is why the Trump administration was so easily able to dismantle it.

Explanation: A good thesis statement does not just make a broad claim, but hones in on the specific issues at hand, especially in an argumentative essay.

Persuasive Essays

Weak: You should invest in Bitcoin now because the price is only going to be higher later on.

Strong: Although risky, cryptocurrency investments will pay off in the future because they are insulated both from market instability and from global currency fluctuations.

Explanation: The weak thesis statement is simplistic, lacks creativity, and does not effectively lure the reader into the essay. On the contrary, the second statement provides a clear direction for the essay. The reader wants to know how you are going to prove your point.

Expository Essays

Weak: Microsoft’s holistic marketing strategies have paid off for the company, allowing it to regain its competitive advantage and market share.

Strong: Microsoft’s holistic marketing strategies have created a more consistent and relatable brand identity, which proves critical in the age of social media and interactive consumer engagement.

Explanation: In an expository essay, you want to explain both why something happens and also how. The weaker of these two thesis statements tells the reader what holistic marketing has done for Microsoft. However, the stronger one states explicitly why holistic marketing is important.

Narrative Essays

Weak: Last summer, I learned about the importance of helping others.

Strong: A major crisis situation encourages us to dig deep, finding an inner source of strength and determination that can be used to uplift, inspire, and empower other people.

Explanation: By now you can recognize that the weaker of these two statements lacks specificity. The strong thesis statement provides clarity and nuance, while still remaining concise.

Descriptive Essays

Weak: Defined by their brightly colored plumage and large shape, macaws make great pets.

Strong: Perennially popular as pets, macaws are beloved for their intelligence and ability to learn, their engagement with people, and of course, their gorgeous rainbow colored plumage.

Explanation: Although veering on containing too much information, the stronger of these two thesis statements offers much more detail than the weaker one and drives the essay forward based on this main idea.

Cause and Effect Essays

Weak: As slavery never did align with core Constitutional values, the Civil War was fought ultimately to assert the character of the nation and to enable a strong central government to prevent the encroachment of universal rights and freedoms.

Strong: The Civil War was fought ultimately to enable a strong central government to prevent the encroachment of universal rights and freedoms, but failed to resolve racism.

Explanation: The weaker thesis statement is overly cluttered, unclear, and inconsistent. The stronger thesis statement illustrates the causes of the war, and also touches lightly on some of the effects, or lack thereof.

Word of Advice:

When you write your thesis statement, ask yourself if it ticks all of these boxes:


A good thesis statement is concise. However, one of the most challenging things about writing a good thesis statement is packing in all the information into one single sentence. With practice, you will find that the adage “keep it simple, stupid” applies well in thesis statement construction. The thesis statement is your main argument. A poorly written thesis statement is clunky, whereas a good one is concise, pithy, and succinct.


All good thesis statements are clear and detailed. Almost by definition, a thesis statement conveys a sense of clarity and purpose in your essay. The best way to be clear when writing your thesis statement is by choosing the brightest words possible. A poorly written thesis statement is nebulous or obscure, whereas a good thesis statement makes it abundantly clear what you are going to say in your essay.

Consistent and Coherent

You would be surprised how many thesis statements are inconsistent with the remainder of the essay. One way a thesis statement can cohere with the rest of the essay is with tone, and another way is with content. The tone of the thesis statement should be consistent with the tone of the rest of your introduction and the rest of the essay. Likewise, the content of your thesis statement should accurately communicate your main arguments. If necessary, you can always revise your thesis statement later if you find that it is not logical or coherent. A poorly written thesis statement has nothing to do with the rest of the essay, whereas a good thesis statement is logically consistent and coherent.


The best thesis statements stand out from the crowd. Be creative, and do not be afraid to make a stand. You can be a little controversial when writing your thesis statement, because your reader will be much more interested in what you have to say if you are saying something unique. Of course, some academic essays ask stock questions. When answering those stock questions, though, it helps to offer a new perspective.

Common Mistakes to Avoid

 1.Vague Language

Avoid words like “good” or “bad.” Be specific.

    • Weak: Uncle Jerry was always a good guy, which is why the townsfolk were so devastated by his death.
    • Strong: Previously torn apart by poverty and pessimism, our community came together to honor the life of Uncle Jerry because his organization the Sunshine Center had touched the lives of almost every resident.
    • Explanation: The former thesis statement lacks specificity. Even a narrative essay needs a strong and almost controversial thesis statement. In this case, the writer claims that Uncle Jerry was almost single-handedly responsible for bringing together a fragmented community.

2.Too Broad or Too Narrow

A thesis should be focused yet broad enough to explore multiple facets.

  • Weak: The short story by Charlotte Perkins Gilman, “The Yellow Wallpaper,” uses literary devices like simile and symbolism to show that the society oppresses women by labeling them as crazy and trapping them into a domestic life.
  • Strong: In “The Yellow Wallpaper,” Charlotte Perkins Gilman delivers a scathing commentary on patriarchal social norms and institutions using potent literary symbolism and metaphor.
  • Explanation: Both thesis statements contain a lot of information, but the second one pares it down, offering a more concise road map for the expository essay.

3.Lack of Argument or Claim

Ensure your thesis makes a clear argument or claim.

  • Weak: Iran and Saudi Arabia are waging proxy wars in Yemen, Syria, and perhaps even Bahrain, reflecting the Sunni-Shia divide and creating tremendous instability in the region.
  • Strong: By arming and training insurgents and fomenting political unrest, Saudi Arabia and Iran are vying for regional dominance.
  • Explanation: The weaker thesis statement rambles, lacks focus or clarity, and fails to actually make a statement. The second thesis statement shows how the writer will focus more exclusively on how the proxy wars are being waged and also why.

Refining Your Thesis Statement

Revision Tips

Refining your thesis statement is ultra-important because no statement is perfect right out of the gate. Start by revisiting your statement after writing your first draft. You’ll have a much better idea of what your paper actually does, and it will be easier to refine your thesis as a result.

Make sure your thesis statement is specific, clear, and debatable. Ask yourself if it directly addresses the essay prompt and if it makes a compelling argument. Simplify complex sentences and remove vague language. Consider feedback from peers or mentors and be open to making adjustments.


  • Clarity: Is the thesis statement clear and easily understood?
  • Specificity: Does it address a specific aspect of the topic?
  • Argument: Does it make a clear, arguable claim?
  • Focus: Is it focused and not too broad or too narrow?
  • Relevance: Does it directly relate to the essay prompt or question?

If you follow these tips and using the checklist, your thesis statement will be strong and effective.

Using Thesis Statements in Your Essay

Placement in the Introduction

Students are usually asked to place their thesis statement at the end of the introduction to their paper. There is a reason for this general rule. The introduction sets the stage—then the action commences (i.e., the body of the essay). Think of the thesis statement almost like the chorus of your favorite song. A song would seem weird if the chorus came first. The chorus of the song is like a thesis statement, adding structure and providing the main point of the composition.

Supporting with Evidence

Each body paragraph should support the thesis statement by presenting evidence and analysis. The best way to do this is to start with a topic sentence that relates directly to the thesis, followed by evidence such as quotes, data, or examples. Then, analyze the evidence and explain how it supports your thesis. In this way, each paragraph stays focused and comes across coherently.

Revisiting in Conclusion

In your conclusion, reinforce your thesis by summarizing the main points of your essay and restating the thesis in a new light. This reminds the reader of your central argument and quickly shows how you have supported it throughout the essay. Tip: Avoid introducing new information; instead, synthesize what has already been discussed.
