From Proto-Balto-Slavic *keʔs-, probably from Proto-Indo-European *k(ʷ)eh₁s-. Cognate with Old Prussian kīsman (time) and possibly Albanian kohë (time). Akin to *čajati (to wait, expect) and *čakati, with a semantic development similar to the one found between *godъ and *žьdati (to wait).

The other possibility is from the lengthened grade of Proto-Indo-European *kes- (to go), wit a semantic development similar to the one found in Latin annus (year) (< earlier *atnos < PIE *h₂et- (to go); compare Sanskrit अटति (átati, to go)).


*čàsъ m

  1. time
