Himalayan Linguistics

This paper studies two grammatical cases in the Gansu-Qinghai linguistic area. Accusative-dative, a syncretic case largely attested in Sinitic languages, is also found in Bao’an and Tu, even if in a very limited use. The Sinitic languages have acquired this syncretic case marking through pattern reduplication due to language contact, while Bao’an and Tu have this innovation owing to the internal mechanisms of their language. The second phenomenon concerns possessor constructions in which the subject-possessor must be marked by a dative case. This marking is seen in all non-Sinitic languages in the Gansu-Qinghai linguistic area and has begun to appear in Sinitic languages. Multiple paths for borrowing between and inside languages in this area present an intertwined model of language borrowing. Linxia City and its closest counties should be the spreading center of these new syntactic devices, and Muslim populations speaking different languages may form a spreading net.
