From Proto-Hellenic *-kos, from Proto-Indo-European *-kos, *-ḱos.
Cognate with Latin -cus, Proto-Germanic *-gaz, Sanskrit -शस् (-śas) and Old Church Slavonic -ъkъ (-ŭkŭ).
PIE *-ko- on noun stems carried the meaning 'characteristic of, like, typical, pertaining to', and on adjectival stems it acted emphatically.
-κός • (-kós) m (feminine -κή, neuter -κόν); first/second declension
Note: This suffix survives in inherited forms and became productive through its derivations (cf. infra) by metanalysis.
