Root Explanation

Undetected → It is formed from "un-" (meaning not) and "detected" (from Latin "detegere", meaning to uncover or reveal). The word "undetected" means not uncovered or not revealed, indicating something that has gone unnoticed.

Memory Tip

Think of something that is 'not' ('un-') 'revealed' ('detected') — that's why undetected means it hasn't been noticed.
