Комментарии:A Mong.-Tung. isogloss. Not quite secure: the TM forms can be alternatively derived from *čiKü-ki, a diminutive of *čiKi (*čiKü) 'pivot' (q. v. sub *č`ĭ̀k`o ); cf. with the same anatomical meaning Ewk. čiki, Ewn. čị̄q, Neg. čịx, Ud. cigi (ТМС 2, 391, Корм. 310). For this etymological direction see Дыбо 1988, p. 120.
