Comments: EAS 154, VEWT 287, KW 236, Владимирцов 168, 324, Poppe 56, АПиПЯЯ 288. A Western isogloss. Despite Щербак 1997, 128, Doerfer TMN 3, 641-642, MT 99 and Rozycki 145 there is no need to assume Mong. < Turk. or TM < Mong. (although it cannot be excluded). Derived are probably bird names: Turk. *gȫkerčin 'dove', *gȫkel 'he-duck', ТМ *kukēkī 'jay', Mong. *kögürǯegene 'dove' (see Лексика 175; Mong. is hardly borrowed < Turk., despite Clark 1980, 44).
