Ramu languages


The Ramu languages are a family of some thirty languages of Northern Papua New Guinea. They were identified as a family by John Z'graggen in 1971 and linked with the Sepik languages by Donald Laycock two years later. Malcolm Ross classifies them as one branch of a Ramu – Lower Sepik language family. Z'graggen had included the Yuat languages, but that now seems doubtful.
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.

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.
Languages of the Ottilien family share plural morphology with Nor–Pondo.

Late 20th century

included the Arafundi family, apparently impressionistically, but Arafundi is poorly known. Ross retains it in Ramu without comment, but Foley and Usher reject inclusion. Laycock also includes the Piawi languages as a branch, but Ross, Foley and Usher all reject their inclusion.

Usher (2024)

Usher breaks up the Grass/Keram family. His classification of Ramu as of 2018 is as follows:
provides the following classification, with 5 main branches recognized.
Tamolan languages and Tangu languages are sparsely documented, and are mostly attested by short word lists.
Grass languages are lexically divergent, sharing very few cognates with the other Ramu languages, with Banaro and Ap Ma sharing almost none. Foley 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 for Proto-Ramu are:
However, Grass languages have the innovations *ɲi ‘’ and *re ‘’.

Cognates

Proto-Ramu forms that are widespread across the family are:
Foley also reconstructs 7 vowels for proto-Ramu:
This 7-vowel system is also typical of Ndu languages.
