Ergative marking in Tibeto-Burman

This paper presents the first results of a comprehensive project on comparative Tibeto-Burman (TB) morpho-syntax. Data on morphological forms and typological patterns were collected from one hundred fifty-one languages and dialects in the TB family. For this paper the data were surveyed for nominal 'ergative' or agentive case marking (postpositions), in an attempt to determine if it would be possible to reconstruct an ergative case marker to Proto-Tibeto-Burman (PTB), and in so doing learn more about the nature of grammatical organization in PTB. Ablative, instrumental, genitive, locative, and other case forms were also surveyed for possible cognacy with ergative forms, as suggested in DeLancey 1984
