Proto-Altaic: *k`i̯ŭ́jŕo
Meaning: cold wind, fog, North
Russian meaning: холодный ветер, туман, север
Comments: Дыбо 45. The root contains a rare cluster *-jŕ-. The Jpn. form can belong here if *-ri is originally suffixed (which is in fact quite probable, given the exceptional structure of the word with medial -ui- ~ -ǝi-).
