Comments:The Turkic form may belong here if it represents a secondary development *bu(-n) 'this' < *bun 'self'; the vocalism, however, speaks against the comparison (*bạ(-n) would be expected). The root reveals contaminations with *méŋu 'whole' q. v. Illich-Svitych (ОСНЯ 2, 70) compares the Turk.-Mong. stem with PKartv. *m(a)-, PU *mū / *mō etc.
