Wena

Wena (also known as Hibu, Hibuese, Mannenese or Nenge) is a language isolate spoken by around 60,000 people on the Hibu Islands in the Hibu Province of Papua New Guinea. It is called by its speakers either nenge wena or nenge wana, both essentially meaning 'our language', the former using the exclusive word 'we, not you' and the latter using the inclusive word 'we, including you'. The closest land to the Hibu Islands is Simberi Island about 150 kilometres to the southwest. Nuguria Atoll is a similar distance away to the southeast. About half of the Wena people are monolingual, the other half also having knowledge of Tok Pisin and a much smaller percentage know English. Dialectal differences are little-documented and appear to be small, most likely owing to the high degree of travel around the island.

Wena appears to be a language isolate. It is a right-branching, strongly isolating language, notable for its largely oligoanalytic nature, its complete lack of verbs other than the non-inflecting copula i, and for its sex-based speech registers, whereby initiated men pronounce all consonants other than /h/ as voiced.
