Languages

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]

• Rai Coast
  • Pulabu
  • Evapia–Kabenau
    • Evapia River
      • Kow
      • Kesawai, Sausi
    • Kolom (Migum), Siroi
    • West Kabenau River: Arawum–Lemio, Dumpu
  • Brahman – Peka River
    • Brahman: Biyom, Tauya
    • Peka River
      • North: Sumau, Sop (Usino)
      • South: Danaru, Kobuga (= Urigina?)
  • Nuru River
    • Uya (Usu)
    • Kwato (Waube)
    • Lower Nuru River: Ogea (Erima), Uyaji–Amowe
  • Awung–Guabe Rivers
    • Awung River: Jilim, Among (= Rerau?)
    • Yangulam

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.
