Комментарии:ТМС 1, 108 (TM-Mong.). An expressive root with difficult reconstruction. The two variants in Mong. and TM are probably due to interdialectal borrowing, but direct borrowing from Mong. into TM is hard to justify: the meanings are not in mutual correlation (Mong. bilka- is 'overflow', while bilki- in TM is 'to wet, moisten'; Mong. bulka- is 'to dip, rinse', while TM bulku- is 'to splash'). The Korean reflex is not quite certain (Martin KED 836 considers pulli- to be a factitive of pūd- 'swell' - which is, however, somewhat questionable).
