|Linguistic classification:||a primary family of Papuan languages|
The Sepik languages are a family of some 50 Papuan languages spoken in the Sepik river basin of northern Papua New Guinea, proposed by Donald Laycock in 1965 in a somewhat more limited form than presented here. They tend to have simple phonologies, with few consonants or vowels and usually no tones.
The Sepik languages, like their Ramu neighbors, appear to have three-vowel systems, /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 /ɨ/ epenthetic (Foley 1986).
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. The proposal is based on similar pronoun paradigms, but its internal structure is subject to revision. According to Ross, the most promising external relationship is not with Ramu, pace Laycock, but with the Torricelli family.
In the cladogram below, the small "families" at the ends of the branches are clearly valid units. Higher nodes (Upper Sepik, Middle Sepik, Sepik Hill) are less certain; Ethnologue (2009) accepts only Sepik Hill, Foley (2005) Sepik Hill and Middle Sepik.
The pronouns Ross reconstructs for proto-Sepik are:
I *wan we two *na-nd, *na-p we *na-m thou (M) *mɨ-n you two *kwə-p you *kwə-m thou (F) *yɨ-n, *nyɨ-n he *ətə-d, *də they two *ətə-p, *tɨ-p they *ətə-m, *tɨ-m she *ətə-t, *tɨ
Note the similarities of the dual and plural suffixes with those of the Torricelli languages.
