Word OriginMiddle English (originally in the sense ‘belonging to one's own private circle’): from Old French prive ‘private’ (also used as a noun meaning ‘private place’ and ‘familiar friend’), from Latin privatus ‘withdrawn from public life’, a use of the past participle of privare ‘bereave, deprive’, from privus ‘single, individual’.
