Root Explanation

Clueless is formed from "clue" (from Middle English *clew*, meaning a ball of thread or a hint) and the suffix "-less" (meaning without). The word describes a state of being without a clue or hint, indicating ignorance or lack of understanding.

Memory Tip

Think of being 'without' ('-less') a 'hint' ('clue') — that's why clueless means lacking understanding.
