What is Paragraph Structure?

Paragraph structure is the organized arrangement of sentences within a paragraph — a topic sentence states the main idea, body sentences develop it with evidence, and a concluding sentence links it to the essay. Proper structure ensures coherence and readability.

Short answer

Paragraph structure has three parts: topic sentence (main idea), supporting sentences (details and examples), and a concluding or linking sentence. This order creates clarity and flow.

Classic Paragraph Structure
  1. 1
    Topic Sentence
    State the main idea clearly
  2. 2
    Supporting Sentence 1
    Add evidence, example, or reason
  3. 3
    Supporting Sentence 2
    Expand with more detail
  4. 4
    Supporting Sentence 3
    Reinforce or add nuance
  5. 5
    Concluding Sentence
    Recap and link to thesis

Topic: 'Social media is a double-edged tool—powerful for connection but risky for wellbeing.'
Support 1: 'Platforms enable long-lost friends to reconnect and marginal communities to find voice.'
Support 2: 'However, algorithm-driven feeds fuel envy, addiction, and misinformation spread.'
Support 3: 'Mental health, especially in teens, suffers from constant comparison and cyberbullying.'
