Root Explanation
Semaphore → It is formed from "sema" (from Greek "σημεῖον", meaning sign) and "phorein" (from Greek "φορεῖν", meaning to carry). The word describes a system that carries or conveys signals, typically through visual means such as flags or lights.
Memory Tip
Think of a 'sign' ('sema') being 'carried' ('phorein') to communicate information — that's what a semaphore does.
