καιρός

See also: καῖρος

Ancient Greek

Etymology

Of unclear origin. Possibly related to κείρω (keírō, “to shear, cut short”) (as a "decisive moment"), κεράννυμι (keránnumi, “to mix”) (as an "atmospherical mix"), or κύρω (kúrō, “to meet (accidentally)”); Beekes seems to favor the connection to κείρω (keírō) the most. Might also be related to, or the source of, Albanian qëro (“time”) (an archaic term).
