Why this word is great
ANTISTROPHON — [Noun] A counterargument that turns an opponent’s own reasoning against them, a rhetorical boomerang. From Ancient Greek ἀντίστροφος (antístrophos, "turned towards each other"), from ἀντί (anti, "against") + στρέφω (stréphō, "to turn"). Unlike "rebuttal" (which merely disputes) or "parry" (which deflects), antistrophon seizes the blade of the original argument and reverses its thrust. It is the lawyer exposing a witness’s contradiction with their own prior testimony, the philosopher dismantling a premise by following it to absurdity, or the child who, when scolded for hitting, asks why it’s wrong for them but not for the parent who just spanked. To wield antistrophon is to reveal that every attack contains the seeds of its own undoing.
