Комментарии:EAS 50-51, Poppe 22, 74, Дыбо 13, Мудрак Дисс. 186; TMN 4, 186 ("lautgesetzlich unwahrscheinlich"). A Western isogloss. The Turk. reflex of the root is usually assumed to be *jālga- 'to lick' - which, however, also matches very well PA *ǯā́lV 'saliva, swallow' and should be rather attributed there. In Pre-Turk. we have to postulate a semantic shift 1) 'lick' > 'bite'; 2) 'saliva(te)' > 'lick'.
