Dibiyaso language
Dibiyaso  Bainapi is a Papuan language of Western Province, Papua New Guinea (Bamustu, Makapa, and Pikiwa villages). Classification
It is sometimes classified with the Bosavi languages. Søren Wichmann (2013) tentatively considers it to be a separate, independent group. Pawley and Hammarström (2018) note that similarities between Bosavi and Dibiyaso are likely due to loanwords, therefore leaving Dibiyaso as unclassified. There is 19% lexical cognacy with Turumsa, suggesting contact or perhaps even a genetic relationship Doso–Turumsa language. Distribution
Dibiyaso is spoken in Bamustu (), Makapa (), and Pikiwa () villages of Gogodala Rural LLG, Western Province, Papua New Guinea. Vocabulary
