Comments:SKE 237, EAS 71, Martin 245. Doerfer (TMN 3, 252) protests against comparing Turk. and Tung. because TM *u (Benzing's *ö) does not correspond to PT *ü. This is of course not true; but the root still has a slight irregularity, namely, high tone in Korean (generally not typical for a verbal root, and not corresponding to Turkic length).
