The thesis is the most important part to your essay. It tells the reader what exactly your essay will be about and provides a basic structure for your essay that provides a strong foundation for your writing. The best way I can explain a thesis statement is that it is usually a one sentence statement that directly states what your essay is about.
In order to write a strong thesis statement you have to have a firm grasp of what your essay is about in order to condense it down into one sentence. A great way to do this is to think of your essay as an answer to a question. In some cases an essay is directly answering a question posed by a teacher or professor, but other times you write an essay that does not have a question directly associated with it. If that’s the case, imagine that your essay is answering a question. Write that question down. Then, answer that question, as completely as possible in one sentence. If you can do that you will be able to write a strong thesis.
In order to write a strong thesis, pretend that your entire essay is answering a question and then answer that question in one sentence.
