With no comprehensive grammar yet available for any of the Ramu languages, the Ramu group remains one of the most poorly documented language groups in the Sepik-Ramu basin.[1]
Classification
The small families listed below in boldface are clearly valid units. The first five, sometimes classified together as Lower Ramu, are relatable through lexical data, so their relationship is widely accepted.[2]
Languages of the Ottilien family share plural morphology with Nor–Pondo.
Laycock (1973) included the Arafundi family, apparently impressionistically, but Arafundi is poorly known. Ross (2005) retains it in Ramu without comment, but Foley (2005) and Usher reject inclusion. Laycock (1973) also includes the Piawi languages as a branch, but Ross (2005), Foley (2005) and Usher all reject their inclusion.
Usher (2024)
Usher breaks up the Grass/Keram family. His classification of Ramu (with both his own and traditional names) as of 2018 is as follows:[3]
Grass languages are lexically divergent, sharing very few cognates with the other Ramu languages, with Banaro and Ap Ma sharing almost none. Foley (2018: 205) leaves open the possibility of Grass being a third branch of the Lower Sepik-Ramu family, with Lower Sepik and Ramu being sister branches.
Pronouns
The pronouns reconstructed by Ross (2005) for Proto-Ramu are:
I
*aŋko, *ni
we two
*a-ŋk-a
we
*ai, *nai, *a-ni, *na-ni
thou
*un, *nu
you two
*o-ŋk-oa, *no-ŋk-oa
you
*ne, *u-ni, *nu-ni
s/he
*man
they two
*mani-ŋk ?
they
*mə, *nda, *manda
However, Grass languages have the innovations *ɲi ‘1SG’ and *re ‘3SG’.[1]
