Greater Binanderean languages

The Greater Binanderean languages, also called Guhu-Oro, are a language family spoken along the northeast coast of the Papuan Peninsula, the Bird's Tail of New Guinea, and appear to represent a relatively recent expansion from the north. Stephen Wurm in 1975 and Malcolm Ross in 2005 classified them as a branch of the Trans-New Guinea languages, but Timothy Usher removed them, along with the related Goilalan languages, from that family in 2020; the core Binandere family itself is considered transparently valid, and Ross's proposed link to the Guhu-Samane isolate on pronominal evidence was confirmed by Smallhorn in 2011, whose work also reconstructed Proto-Binanderean excluding Guhu-Samane.
