Case markers of personal pronouns in Tibeto-Burman languages

Some Tibeto-Burman (henceforth TB) languages possess an inflectional category of case in their personal pronouns. These case distinctions are marked by morphophonemic changes affecting the initial consonant, rhyme, and/or tone of the pronoun. The present paper deals with the varying forms, origins and other problems concerning the case category for personal pronouns in TB languages.
