Comments:Лексика 168. Low tone in Jpn. does not correspond to Kor. (but cf. different dialectal variants). The root must have denoted some small rodent, possibly a flying squirrel (which could explain the meaning 'bat' in Turkic). One should also mention PM *ǯaraɣa 'hedgehog, porcupine' = Karakh. jarpuz 'mongoose', possibly derived from the same root. A different etymology of the Turkic word (comparing it with Evk. ńarbakin 'naked' and deriving from a *ńarV 'naked skin', see Stachowski 1999) seems less likely to us.
