Root Explanation

Countersign → It is formed from "counter-" (meaning against or opposite) and "sign" (from Latin "signum", meaning mark or sign). The word refers to a sign or mark that is used to verify or authenticate another sign, acting as a counter or opposing verification.

Memory Tip

Think of a 'sign' that acts 'against' or verifies another sign — that's what a countersign does.
