Linguistic classificationNortheast New Guinea?

The Rai Coast languages are a family of languages in the Madang stock of New Guinea.

Sidney Herbert Ray identified what was then known of the Rai Coast languages as a unit in 1919. They were linked with the Mabuso languages in 1951 by Arthur Capell in his Madang family.


Though the validity of Rai Coast is well established, there are ongoing adjustments to membership and internal classification. Malcolm Ross added two languages to Rai Coast, Tauya and Biyom, from the small erstwhile Brahman branch of Madang.

The languages are as follows,[1]

Ross (2000, 2005) reconstructs pronouns for proto-Sub-Rai, which is more-or-less synonymous with Rai Coast as a whole, proto-Mindjim, proto-Yaganon, and proto-Kow–Usino.
