τηρός

Ancient Greek

Etymology

Apparently from Proto-Indo-European *kʷeh₁y- (“to perceive”), and compared with Sanskrit चायति (cāyati, “to observe, perceive”) and Proto-Slavic *čajati (“to wait, expect”). However, this is phonetically unsatisfactory, as the Greek term shows no trace of the root-final *-i-.^[1]
