Wandamen

Wamesa is an Austronesian language of Indonesian New Guinea, spoken across the neck of the Doberai Peninsula or Bird's Head. There are currently 5,000–8,000 speakers. While it was historically used as a lingua franca, it is currently considered an under-documented, endangered language. This means that fewer and fewer children have an active command of Wamesa. Instead, Papuan Malay has become increasingly dominant in the area.
