The Grass languages are a group of languages in the Ramu language family. It is accepted by Foley (2018), but not by Glottolog. They are spoken in East Sepik Province, Papua New Guinea, with a small number of speakers also located just across the provincial border in Madang Province.


The original Grass-language proposal, also known as Keram, included several languages, such as Banaro and Kambot (Ap Ma), that are no longer thought to be closely related to Adjora and Gorovu.

Laycock (1973)[edit]

Laycock (1973) rejected Kambot and noted that Banaro was lexically divergent, and therefore grouped it with the Grass family in a higher-level Grass stock,[1] a position accepted by Pawley (2005).[2]

Usher (2018)[edit]

Timothy Usher (as reported in Glottolog) broke it up still further, with only Abu (Adora) and Gorovu kept together (in a "Porapora River" or "Agoan" branch),[3] Aion (Ambakich) and Kambot (Ap Ma) grouped with the Mongol–Langam languages, and Banaro left as a primary branch of Ramu proper.[4]

Foley (2018)[edit]

Foley (2018) provides the following classification.[5]
