Root Explanation

Duplicate → It is formed from "dupli-" (from Latin "duplex", meaning twofold or double) and "-cate" (from Latin "catum", meaning to make). The word "duplicate" means to make a copy or to create something that is twofold or double.

Memory Tip

Think of something being made "twofold" or "double" — that's why duplicate means to create a copy.
