7.B Chiasmus and Antimetabole

A straight repetition just says the same thing twice. A chiasmus flips the order: idea one, then idea two, then idea two again, then idea one again, so the second half mirrors the first in reverse. Picture it as an X — the terms literally cross. That crossing does rhetorical work. Instead of a writer telling you something is true, the sentence seems to prove itself by showing both arrangements side by side, the right one and the wrong one, and lets you watch the right one win.

Antimetabole is the specific, stricter version: the exact same words return, but in swapped grammatical roles. 'Eat to live, not live to eat' repeats 'eat' and 'live' but trades which one is the goal and which is the method. Because you see the rejected order right next to the endorsed one, the sentence feels like a demonstration, not an opinion — you watched the logic flip, so it seems earned rather than handed to you. That's why slogans and maxims lean on it: compressed, memorable, self-certifying.

This sits beside anaphora and parallelism in the family of balance schemes, but it does something they don't. Anaphora repeats the same opening to build momentum in one direction; parallelism lines up equal structures without reversing them. Chiasmus and antimetabole specifically reverse, which is what creates the sense of a discovered truth rather than an asserted one. Spotting the difference matters for reading how an author wants a claim to land — as momentum, as balance, or as proof.
