mind
/maɪnd/·마인드·noun
the part of a person that thinks, feels, perceives
Old EnglishCEFR A2
Root
Proto-Indo-European '*men-' (to think)
PIE *men- (to think) → Proto-Germanic *gamundiz (memory) → Old English gemynd (memory, intention) → Modern mind. Latin retained the same root in mens/mentis (mental, mention).
In a word
This word is a rare case in which Germanic and Latin grew side by side from one Indo-European root. PIE *men- (to think) → Germanic branch: gemynd → mind. Latin branch: mens/mentis → mental, mention, and the wider family. "Mental" and "mind" are siblings raised on different branches — and English eventually gathered both into the same sentence.
Examples
Keep an open mind.
She changed her mind.
It slipped my mind.
