Comments:Владимирцов 213, Poppe 127. Despite TMN 3, 586, Щербак 1997, 128, Mong. cannot be borrowed from Turk. Also, despite MT 136, Jurch. hufuru cannot be a Mong. loanword. In Jpn. we would rather expect *kupara; the -a- vocalism is either a result of later assimilation (in a long word), or an influence of *kápá 'river' (different etymologically, see *k`ébà).
