Proto-Slavic

Etymology

Inherited from Proto-Balto-Slavic *-āˀkas, from Proto-Indo-European *-eh₂kos, *-eh₂ks. Deverbal derivations are easily secondary, motivated by parallel formations, e.g.

North Slavic *ědakъ (“greedy man”) ← *est < *ed-ti (“to eat”) : *ěda (“food”).

Comparison with cognates in other Indo-European languages indicates antiquity of deadjectival formations:

Ancient Greek νέος (néos, “new, young”) → νέᾱξ (néāx), νέᾱκος (néākos, “young man”) : Slavic *novъ (“new”) → *novakъ (“novice”)
Lithuanian naũjas (“new”) → naujõkas (“novice”)

Cognate with Proto-Celtic *-ākos (see Etymology 2).
