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’).
eş: манипулятор, организатор, кукловод, руководитель
köken: Probably an inner-Russian formation based on дирижи́ровать (dirižírovatʹ) + -ёр (-jór). The usual corresponding French term is dirigeant, not the quite rare or marginal dirigeur. Some steps omitting, from Latin dīrigō (whence also дирижа́бль (dirižáblʹ)); also note p.p.p. dīrēctus (whence дире́ктор (diréktor) and many others).
