I noticed a strange duplication in the data we collected.

Really? That could mess up the results if we don't fix it.

Yeah, I think we need to double-check everything for any other duplication issues.

Root Explanation

Duplication → It is formed from "duplex" (from Latin, meaning twofold or double) and "-ation" (a suffix used to form nouns indicating an action or resulting state). The word "duplication" refers to the act or process of making a copy or doubling something.

Memory Tip

Think of something being made 'twofold' ('duplex') — that's why duplication means creating a copy or doubling something.
