7.A Building a Body Paragraph (LAN-1.C)

A body paragraph is not a container for a quotation. It is an argument in miniature, built from four parts that depend on each other. The topic sentence makes a claim, something a reader could push back on. The evidence, usually a quotation, gives the reader something specific to look at. The commentary is where the actual thinking happens: it says what the evidence means and how it proves the claim. The link closes the paragraph by pointing toward the next claim, so the essay keeps moving instead of restarting. Take away the commentary and the other three pieces stop touching each other. You are left with an assertion, a quotation sitting next to it, and a sentence gesturing at what comes next, but nothing has actually been argued.

The order matters because each part makes the next one usable. The claim tells the reader what to watch for. The evidence gives them the material. The commentary interprets that material in light of the claim, explaining, not repeating it in different words. The link then takes that interpretation and uses it to set up whatever the paragraph after this one will argue. Skip a step and the reader has to do the paragraph's work themselves.

This is why a topic sentence that only previews content, like saying a paragraph will look at several references to something, fails before it starts. It commits to nothing. A real topic sentence stakes a claim the rest of the paragraph has to defend, which is what gives the commentary something to prove and the link something to carry forward into the essay's larger argument.
