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:

In academic essays, if your teacher has not assigned a topic, you would have to come up with an interesting topic for your essay. You should choose the topic after thorough research so that you are confident about the topic while writing your essay. Moreover, it would be best if you determined whether the essay is expository, argumentative, or analytical 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 in which your essay will continue from this step onwards.

Step # 4 – Add reasoning to your answer:

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

It should be:

  • A single sentence in which the entire central idea of the essay should be presented.
  • An arguable statement instead of a factual one, and it should be supported by evidence.
  • Specific; this means that you must include a particular aspect and leave everything else that is irrelevant to your chosen aspect.
  • Precise and focused on the main topic, and it should formulate a stance.
  • Never be vague, judgemental, or combative. Any claim you make should be supported with enough reasoning and evidence.
