Mapos Buang, also known as Mapos or Central Buang, is an Oceanic language in Morobe Province, Papua New Guinea.


Mapos Buang has a larger sound inventory than is typical of most Austronesian languages. Notable is the existence of a phonemic uvular nasal, and a distinction between a voiced bilabial fricative and a bilabial approximant (although the approximant can be analyzed phonologically as labio-velar).

* [ə] is a prominent feature of Buang phonology, but is not contrastive.

*/w/ is a bilabial approximant or semivowel with no co-articulated velar component. It is placed in the labio-velar series of the chart as it fills a gap in this position. /β/ is a voiced bilabial fricative.
