Comments:Whitman 1985, 139, 245 (Kor.-Jpn.). Loss of final resonant in Kor. makes us reconstruct the medial -j-, which also explains several other phenomena: *-i-vowel in PTM (-u- would be expected after a labial); *b- in PJ (*p- would be expected before i). Korean has also lost the initial *b-, as in some other cases; cf. in this respect the interesting Old Koguryo and Silla forms: Old Koguryo *wöl, Silla *ŏl (see Miller 1979, 9). Jpn. *bì < *bi̯ujr(i)-gV.
