family=a primary family of Papuan languages
child8=Sepik HillThe Sepik languages are a proposed family of some 50
Papuan languagesspoken in the Sepik river basin of northern Papua New Guinea. The languages tend to have simple phonologies, with few consonants or vowels and usually no tones.
The best known Sepik language is Iatmül. The most populous are Iatmül's fellow
Ndu languagesAbelam and Boiken, with about 35 000 speakers apiece.
The Sepik languages, like their Ramu neighbors, appear to have three-vowel systems, IPA|/ɨ ə a/, that distinguish only
vowel height. Phonetic [i e o u] are a result of palatal and labial assimilation to adjacent consonants. It is suspected that the Ndu languages may reduce this to a two-vowel system, with IPA|/ɨ/ epenthetic.
The classification used here is that of
Malcolm Ross. It consists of two branches of Laycock's Sepik-Ramu proposal, the Sepik subphylum and Leonhard Schultze stock. The latter has been tentatively broken up by Ross into its constituent families, Walio and Papi, with Papi reassigned to the Sepik Hill branch of Sepik.
According to Ross, the most promising external relationship is not with Ramu but rather with the Torricelli family.
The small families listed in boldface are clearly valid units. The overall family is based on similar
pronounparadigms, but its internal structure is subject to revision.
