Northwest Papuan languages

The Northwest Papuan languages are a proposed family of Papuan languages of Papua Province, Indonesia, developed by Timothy Usher under the name North(west) New Guinea, building on branch relationships H.K.J. Cowan first proposed in the 1950s, a Border-Tor connection Clemens Voorhoeve made in 1971, and pronoun-based links among western Foja Range branches that Malcolm Ross proposed. The grouping comprises the Fas, Sentani, Border (Upper Tami) and Sko families along with the Foja Range, or Tor-Kwerba-Nimboran, branch, whose own members include the Nimboran, Kwerbic, Mawes and Orya-Tor languages; it carries no Glottolog code, and some shared Foja Range vocabulary may reflect borrowing rather than common descent.
