köken: Borrowed from Latin coryphaeus, from Ancient Greek κορυφαῖος (koruphaîos, “leader of the chorus in an Ancient Greek drama”), from κορῠφή (korŭphḗ, “top of the head, crown”) (possibly ultimately from Proto-Indo-European *ḱerh₂- (“head, top; horn”)) + -ῐος (-ĭos, suffix forming adjectives meaning ‘belonging to, relating to’).
