The Foau language, Abawiri, also known as Doa, is a Lakes Plain language of Papua, Indonesia. Clouse tentatively included Abawiri and neighboring Taburta in an East Lakes Plain subgroup of the Lakes Plain family; however, since only very minimal data was available on the languages at that time, the position of Abawiri and Taburta within the Lakes Plain family remains tentative.
Abawiri is notable for its lack of nasal consonants: there are no nasal or nasalized consonants or vowels, even allophonically. Like other Lakes Plain languages, the language is tonal.
