How to Write a Thesis Statement?

You can write a strong thesis statement through the following steps.

Step # 1 – Decide your topic and type of essay:

If your teacher has not assigned a topic in academic essays, you would have to develop an exciting topic for your essay. It would be best if you chose the topic after thorough research to be confident about the topic while writing your essay. Moreover, it would be best to determine whether the essay is expository, argumentative, narrative, literary or rhetorical at the initial stage.

Step # 2 – Formulate a question:

After deciding on your topic for the essay, you need to choose a particular aspect that you will discuss throughout the essay. For this, you should formulate a question that serves as the basis of the thesis statement.

For example, if your essay topic is “junk food,” the question thus formulated can be “is junk food bad for health?” Your thesis statement would be an answer to this question.

Step # 3 – Write an initial answer:

You need to come up with an initial answer that would generally answer your question.

In the case of our chosen topic, your initial answer would be, “junk food is bad for health.”

Through your initial answer, you can decide your stance on the topic and the direction your essay will continue from this step onwards.

Step # 4 – Add reasoning to your answer:

A strong thesis statement also answers “how” and “why”. While claiming on a particular topic, you must provide logical reasoning to make a claim more valid and reliable. The final thesis statement will not just state your viewpoint. Instead, it would back up with reason and summarise the whole discussion.

For example, a developed thesis statement on the topic of junk food can be,
“Although junk food is consumed a lot by people, it is bad for health because it is the basic driving factor towards multiple serious complications such as obesity, type 2 diabetes, and heart diseases.”

Qualities of a good thesis statement:

A strong thesis statement should have the following qualities,

  • A single sentence that presents the central idea of the essay
  • An arguable statement instead of a factual one, and it should be supported by evidence
  • Specific; this means that you must take a specific stance on the topic
  • Precise and focused on the main topic should formulate a stance
  • Never be vague, judgemental, or combative
  • Support your claims with enough reasoning and evidence

To write a thesis statement, identify the main argument of your essay. Make it concise, specific, and arguable. Ensure it reflects the purpose of your paper and provides a roadmap for your ideas. Revise and refine it until it effectively captures the essence of your argument.
