Mwesen shows many similarities with the island's dominant language Vurës, to such an extent that they have sometimes been considered dialects of a single language. However, studies have shown that Mwesen and Vurës have various dissimilarities, e.g. in their vowel systems,[2] in their noun articles,[3] in their pronoun paradigms.[4]
Name
The name Mwesen is originally the name of a village, in the eastern part of Vanua Lava;[5] it is spelled M̄ēsēn[ŋ͡mʷɪˈsɪn] both in Mwesen itself, and in neighbouring Vurës. The village is known as Am̄sēn[aŋ͡mʷˈsɪn] (with locative prefix a-) in Mwotlap, and as M̄osina[ŋ͡mʷosina] (modern: M̄osna[ŋ͡mʷosna]) in Mota. All these different names are derived from a Proto-Torres-Banks form *mʷosina.
The old Mota name M̄osina was the source of Mosina, one of the names which was occasionally given, in English, to the Mwesen language (sometimes encompassing Mwesen together with Vurës).[6]
Spatial reference in Mwesen is based on a system of geocentric (absolute) directionals, which is in part typical of Oceanic languages, in part innovative.[7]
