Comments:ССЕ 267. Not quite clear is the relationship of the forms: Ket. plur. ĺɨkken5, South. ĺɨkŋ5, Yug lɨkŋ5. A change *-tŋ > -kŋ is actually possible in Ket, but a reduplication in ĺɨkken5 is somewhat strange. Besides, Castren has recorded in Kottish one more word with the meaning "mountain": d́ix, plur. d́ekŋ, d́igan. It is possible to reconstruct one more PY root: *ĺɨ(ʔ)k, reflected (besides the forms listed) in the Kott. compound xē-lēx, khē-lēg 'mountain ridge' (the first part see under *qäʔj). On the whole, a rather complicated case. Werner (2, 16) tries to solve it by postulating PY <*ʎɨk, pl. *ʎɨkŋ> and its compound with an unclear component <*ǝt'> (?) - *ʎɨkkǝt' > *ʎɨkt' > Ket ĺɨʔt etc. Such a development would be phonetically unprecedented in Yenisseian.
