Root Explanation

Harmless → It is formed from "harm" (from Old English *hearm*, meaning injury or damage) and "-less" (meaning without). The word "harmless" means without harm or injury.

Memory Tip

Think of being 'without' ('-less') any 'injury' ('harm') — that's why harmless means not causing any harm.
