Comments:EAS 65, KW 479, Владимирцов 197, SKE 31, Poppe 28, 111, Дыбо 13. The comparison seems quite valid, despite doubts in TMN 4, 225. Despite Poppe 1966, 191, Doerfer MT 24, Rozycki 128, TM is hardly < Mong. Loss of *-g- in Turkic is probably explained by the fact that the root is only used with suffixes (*jüg(V)k > *jük, *jüg(V)d > *jüd-).
