Other comments: Mutu has a quinary /vigesimal counting system, the highest number is ndiŋndiŋ. The word one 'ee(z)' also functions as an indefinite article.

Note (2008): Mutu, is one of three dialects of a single language. Locally, these dialects are termed: Oov, Malai, and Tuam.  It seems that "Mutu" is sometimes used to subsume all 3 dialects, and at  other times it refers to only the Oov dialect.  Mutu = 'island' in the Oov and Malai dialects, while Sisi = 'island' in the Tuam dialect. So as a language name, Mutu is not very good for subsuming all 3. Mutu or Tuam (Mutu-Tuam) is spoken by about 3,500 speakers on Umboi island in Morobe Province, Papua New Guinea.
