North New Guinea languages

The North New Guinea languages of Papua New Guinea and Indonesia form a possible linkage of Western Oceanic languages. They have been in heavy contact with Papuan languages.

Classification

According to Lynch, Ross, & Crowley, the structure of the family is as follows:

The center of dispersal was evidently near the Vitiaz Strait between New Britain and the New Guinea mainland.
The inclusion of Sarmi and Jayapura Bay is uncertain, and it may constitute a separate branch of Western Oceanic.
