idiot (English)
Where does "idiot" come from?
The word 'idiot' originates from the Ancient Greek 'idiṓtēs,' which referred to a private citizen who lacked professional knowledge or public standing. It evolved through Latin and Old French into Middle English as a term for someone uneducated, eventually shifting in common English usage to describe a person lacking general intelligence or acting foolishly.
