Root Explanation
Mindlessness → It is formed from "mind" (from Old English "gemynd", meaning memory or thought) and "-less" (meaning without). The word "mindlessness" refers to the state of being without thought or awareness.
Memory Tip
Think of being 'without' ('-less') 'thought' ('mind') — that's why mindlessness means a lack of thought or awareness.
