Topic notes

Main Idea

A thesis statement is the single sentence that tells readers the essay's main argument or claim, guiding every paragraph that follows.

Key Concepts

  • A thesis is arguable, not just a fact
  • It should be specific, not vague
  • Every body paragraph should support the thesis
  • A strong thesis previews the essay's structure

Definitions

  • Thesis statement: a sentence expressing the essay's central, arguable claim
  • Topic: the general subject, different from a specific claim
  • Arguable claim: a statement someone could reasonably disagree with

Structures / Templates

  • Template: 'Although [opposing idea], [topic] because [reason 1], [reason 2], and [reason 3].'
  • Simple template: '[Topic] does X because of Y and Z.'

Examples

  • Weak: 'Social media is popular.' (fact, not arguable)
  • Strong: 'Social media harms teen mental health because it increases comparison, reduces sleep, and fuels anxiety.'

Common Mistakes

  • Writing a fact instead of a claim
  • Being too broad or vague
  • Forgetting to preview supporting reasons
  • Placing the thesis in the wrong spot (should usually end the intro)
