Comments:Poppe 11 compares the Mong. form with TM *pule- which is less likely. Jpn. pà and MKor. pó reflect a contraction < *pi̯ugV-ga. An expressive root with not quite clear vocalic correspondences, rather difficult to distinguish from several similar: cf. *pŏ̀k`è, *p`ū̀gé, *p`àgò.
Comments:The root has a general meaning 'cut' in the Eastern area (TM and Japanese), and a more specialized meaning - 'wound' - in the Turko-Mongolian area; it is not quite clear which one is more archaic.
Comments:The TM form can be compared with Mong. and Kor. if it is a contraction of a suffixed form *t`at`V-gV-. On a possible Japanese reflex see under *č`àro.
