Comments: VEWT 176, EDT 879, 881-882, ЭСТЯ 4, 47-48, 51. Turk. > WMong. ǯabqai, ǯabaɣan (KW 468), whence again some Turkic forms (Kirgh. ǯabɨq etc., see ЭСТЯ 4, 9-10). One could perhaps also note Kaz. žawra-, Uzb. ǯɔwra- 'to suffer from cold, shiver' (ЭСТЯ 4, 20) which may be = Karakh. javra-, javrɨ- and thus should not be compared to Mong. daɣara- (despite KW 82).
