köken: From Proto-Baltic *kur, from the same Proto-Indo-European stem *kʷu-, *kʷo- as the interrogative pronoun kas (q.v.). Cognates include Lithuanian kur̃, Old Church Slavonic къде (kŭde) (cf. Russian где (gde)), Sanskrit कुह (kúha).
köken: Inherited from Old Norse hvart, from hvar (“where”) (whence hvar) + at (“to”) (whence að). The vowel change is probably due to influence from hver (neuter hvert).
