Thesis Statements
A thesis states your main argument in one or two sentences.
About this topic
A thesis statement is one or two sentences, usually at the end of the introduction, stating your central argument or main claim in an essay, and previewing the support. A good thesis is specific, arguable (not a simple fact), focused and answers the question. Weak: "Pollution is bad." Stronger: "Cities should ban private cars from central areas because it would cut air pollution, improve public health and make streets safer."
The thesis acts like a compass for the essay: every paragraph should support it, and it tells readers what to expect. To build one, start with a question, make a claim in answer, and add your main reasons. A thesis can often be improved by asking so what? and how or why? until it says something that a reasonable person could disagree with.
Worked example: for a prompt on a novel, a topic might be "the theme of friendship in Of Mice and Men". A thesis might be "Steinbeck suggests that friendship offers hope in a cruel world, yet shows that dreams shared between people remain fragile." This takes a position that can be argued with evidence.
Common mistakes include announcing ("In this essay I will discuss..."), stating a fact that needs no proof, or being too vague or too broad. Remember that the thesis may be revised after you draft, because writing often clarifies what you actually think.
