Comments:Poppe 63, KW 241, Владимирцов 377; Лексика 490; TMN 3, 633 ("...nicht hinreichend gesichert"). Despite Щербак 1997, 127, not borrowed in Mong. < Turk. (see also Clark 1980, 56); -s- instead of the expected -č- in Mong. is due to a position within the cluster (köske = köčke). -č- (or *-š-) in Evk. is, however, more difficult to account for (*-s- would be expected normally), which means that the Evk. words may actually be borrowed < Yakut.
