Root Explanation

Duplex → It is formed from "du-" (meaning two) and "plex" (from Latin "plicare", meaning to fold). The word "duplex" refers to something that is folded or composed of two parts.

Memory Tip

Think of 'two' ('du-') things that are 'folded' ('plex') together — that's why duplex means something that has two parts.
