The singular oblique pronouns have the so-called pronominal +n+ before the suffix. There are, then, oblique stems bun+ and an+ differing from the nominative stems bo and ol; bo and bun+ also differ in the vowel, alternating like the personal pronoun. The possessive suffixes of the 3rd person show the oblique pronominal /n/ as the demonstratives do. In Uygur, the b becomes m when a nasal follows; this replacement did not yet take place in the inscriptions of the Uygur steppe empire, as shown e.g. in bunda in Tariat W 2.
