Comments:KW 180, Владимирцов 270, Poppe 48. A Western isogloss. Despite Doerfer's doubts (TMN 1, 450), the Turk. and Mong. forms cannot be separated from each other. It is interesting also to mention the forms meaning 'to wink' ( < *'press eyelids together') among the reflexes of PT *Kɨp- (usually confused with *Kɨp- 'spark') and the TM derivative *kapta- (usually confused with *kapta- 'flat'). Cf. also *k`ap`V.
