[2] The Binandere family proper is transparently valid; Ross connected it to the Guhu-Semane isolate based on pronominal evidence, and this has been confirmed by Smallhorn (2011).

For instance, the SOV word order of Papuan Tip languages is due to Binanderean influence.

[3] Spoken in Morobe Province, Guhu-Samane is divergent, which may be due to extensive historical contact with Oceanic languages such as Numbami.

Usher (2020), who calls the Binanderean languages proper "Oro" after Oro Province, classifies them very similarly, apart from not reproducing the non-cladistic linkages:[2] Smallhorn (2011:3) provides population figures for the following Binanderean languages.

Ross (2005) reconstructs both independent pronouns and verbal person prefixes: Only 1sg continues the Trans-New Guinea set.
