Paragraph Structure: Claims, Evidence, Commentary
Every body paragraph needs three layers:
- Claim: A statement that advances the argument
- Evidence: Specific support (quotation, data, example)
- Commentary: Explanation of how the evidence proves the claim and connects to the thesis
Commentary is the reasoning bridge. It shows readers why the evidence matters and how it supports the overarching thesis. Without commentary, evidence sits isolated.
Test yourself: Can you explain how each paragraph's claim and evidence work together to prove the thesis? If not, you need stronger commentary.
