A thesis statement is a sentence, or occasionally two, that states the central argument or main point of an essay or research paper. It usually sits at the end of the introduction and signals the direction the rest of the writing will take.
A strong thesis is specific and arguable rather than a simple statement of fact, giving the reader a clear claim to test against the evidence that follows. Vague thesis statements tend to produce essays that wander without a consistent line of argument.
For example, rather than writing that social media affects teenagers, a workable thesis might argue that social media use correlates with reduced attention spans in secondary school students, a claim the essay can then support with evidence.
Placement can shift with essay type: argumentative and analytical essays place it at the close of the introduction, while some dissertations restate it in the conclusion. Our guide to essay structure shows where it fits alongside the hook and outline.
Students unsure whether their thesis is focused enough often ask a tutor or use our essay topic and outline service to test the argument before drafting the full essay.
