Mali (2,200 speakers) is a Papuan language spoken on the Gazelle Peninsula, East New Britain Province Papua New Guinea. It is a member of the Baining language family. The family is comprised of five languages: Kaket, Mali, Simbali, Ura and Kairak. Baining people share a common non-Austronesian ancestral language and similar cultural practices (such as fire dances). An interesting feature of these languages is that they show a great deal of influence from their early Austronesian neighbors. As detailed in the grammar, Mali has characteristics of both the Western Oceanic branch of Austronesian and Trans New Guinea. This is the first comprehensive grammar for a language from the family and provides a framework for further comparative and descriptive research in the region. The grammar was produced in cooperation with members of the Mali (Baining) community and is being published alongside a dictionary and text collection (also available from Pacific Linguistics).
