köken: Learned borrowing from Koine Greek εὐχαρίστως (eukharístōs, “gratefully”), with semantic loan from French avec plaisir. By surface analysis, ευχάριστος (efcháristos) + -ως (-os).
köken: From Proto-Albanian *gat-, from Proto-Indo-European *gʷem- (“to go”). Cognate to Sanskrit गति (gáti-, “going, course”), Proto-Slavic *gatь (cf.
