Did you see that movie last night?

Yeah, it was pretty mindless, but I enjoyed it anyway.

Root Explanation

Mindless → It is formed from "mind" (from Old English "gemynd", meaning memory or thought) and "-less" (meaning without). The word "mindless" means without thought or lacking in mental activity.

Memory Tip

Think of being 'without' ('-less') 'thought' ('mind') — that's why mindless means lacking thought.
