conclave

Origin

PIE word *ḱóm The noun is derived from Late Middle English conclave (“private chamber; (Roman Catholicism) private room where election of the Pope takes place; meeting held for this purpose”), borrowed from Middle French conclave (modern French conclave), or directly from its etymon Latin conclāve (“chamber, room; enclosed space that can be locked; dining hall”), from con- (prefix denoting a being or bringing together of several objects) (combining form of cum (“(along) with”)) + clāvis (“key”) (ultimately from Proto-Indo-European *kleh₂w- (“(noun) crook, hook; peg; (verb) to close”)). The verb is derived from the noun.
