College Composition
Thesis Statements and Topic Sentences

Overview

Strong essays begin with clear direction. A thesis statement expresses the central argument of your essay, while topic sentences introduce the key ideas in each body paragraph. Mastering both will give your writing clarity, coherence, and purpose from beginning to end.

What Makes a Strong Thesis?

Weak: Social media has changed society.
Strong: While social media promotes connection, it also increases misinformation and reduces face-to-face interaction, making it a double-edged tool for modern communication.

Crafting Effective Topic Sentences

Weak: There are many issues with social media.
Strong: One of the most serious concerns about social media is the rapid spread of false information.

Tip: After writing a draft, check each topic sentence. If it doesn’t relate directly to the thesis or doesn’t clearly introduce the paragraph’s focus, revise it.
