Thesis Statement

A thesis statement states the writer’s central position or assertion and gives the reader a focused sense of the paper’s scope, purpose, and direction. It should be specific enough to support with the evidence and development available in the paper.

Quick answer

A thesis statement makes a focused assertion about the topic and signals the paper’s direction; it should be specific, supportable, and matched to the paper you actually develop.

Important caveats

Scope Boundary

Not every assignment requires an argumentative thesis, and a purpose statement is not identical to a thesis statement.

Further guidance

Application

Revise the thesis as the paper develops so its scope and claim match the evidence and organization of the finished paper.

Core Rule

A thesis statement makes an assertion about a topic rather than merely announcing the topic.
