köken: Of unknown origin. McGregor tentatively postulates a combination of कान (kān, “ear”) + चूसना (cūsnā, “to suck”), lit. "ear-sucked"; compare मक्खीचूस (makkhīcūs, “miser”, literally “fly-sucker”) for a similar formation.
inflection of avārus: · nominative/accusative neuter plural
köken: Possibly an old hydronym from Proto-Indo-European *h₂wer- (“water, rain, flow”), found in cognates such as Sanskrit वार् (vār, “water, pond”), Latin urina, Lithuanian virti (“to seethe, boil, flow”), Old Norse vari (“water”). One of the river's tributaries, Auron, could be a suffixed form of this root *aver-on-.
köken: Derived from Ancient Greek στῡ́φω (stū́phō, “to be harsh, astringent”) + -ца (-ca). Compare the adjective Ancient Greek στυπτῐκός (stuptĭkós, “astringent”).
From Middle Dutch vrec, vrek (“miserly; miser”), from Old Dutch *frek, from Proto-West Germanic *frek, from Proto-Germanic *frekaz. Originally an adjective, but substantivised in early Middle Dutch at the latest. Cognate to German frech (Old High German freh), Old English frec.
