πάτρως

Ancient Greek

From πᾰτήρ (pătḗr, “father”). Compare μήτρως (mḗtrōs, “maternal uncle”). Cognate with Latin patruus (“paternal uncle”), Classical Persian (afdar, “paternal uncle”), and Sanskrit पितृव्य (pitṛvya, “paternal uncle”).

πᾰ́τρως • (pắtrōs) m (genitive πᾰ́τρωος or πᾰ́τρω, variously declined); third declension, second declension

paternal uncle
Synonyms: πᾰτροκᾰσῐ́γνητος (pătrokăsĭ́gnētos), πᾰτρᾰ́δελφος (pătrắdelphos)

Coordinate term: μήτρως (mḗtrōs)
ancestral male relative of one's father
(Cretan) any male relative of one's father

Third declension during the Classical period, but assimilated into the Attic declension in Koine.
