coryphée

coryphée is masculine in French.

leader of the ancient Greek chorus, coryphaeus

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’).
