Comments:KW 234, Дыбо 6, Лексика 280. A Western isogloss, with a rather complicated phonology. In Mong. *köjil-sü ( < *kölil- < *kölin-) should be distinguished from *köji < *kṓp`i, although the reflexes have been significantly confused; PTM *xulŋu- either < *xulnu- through assimilation, or else < *xulnu-gV- or *xulnu-ŋV- (with a fused velar suffix). Finally, in Turkic one has to suppose a (rather frequent) fronting *kīn < *kɨ̄n.
