Thesis statements are advantageous to students because they clearly identify the subject of the paper. Without a thesis to follow, the writer's mind tends to wander off into uncharted territories that skew the essay and throw the reader off track. A succinct and clear thesis narrows the subject such that the student can return to it throughout the paper.
A well-defined thesis statement makes identifiable claims about the subject. These claims enable the writer to expand his argument with discussions that are focused solely on supporting the claims. Such a thesis statement thus both focuses a paper and adds depth to it.
A well-written thesis statement presents a logical order. Following the same logical order throughout the paper makes the discussion flow more smoothly. The writer can return to the thesis statement while writing transitions between different aspects of the paper . A reader who becomes confused while reading the essay can also return to the thesis statement for clarity.
Reader comprehension is enhanced by a well-written thesis statement. By identifying the subject, making claims about the subject and presenting a logical order for discussion, the thesis statement announces all of these aspects of the paper to the reader in a single sentence.
