Have you ever used a field guide to help you identify plants?

Yes, I have one that acts as an identifier for different flowers.

Root Explanation

Identifier → It is formed from "ident" (from Latin "identitas", meaning the same) and "-ifier" (from Latin "facere", meaning to make). The word "identifier" refers to something that makes something the same or identifies it.

Memory Tip

Think of something that 'makes' ('-ifier') something 'the same' ('ident') — that's why an identifier is used to recognize or specify something.
