Mawayana (Mahuayana), also known as Mapidian (Maopidyán), is a moribund Arawakan language of northern South America.
It used to be spoken by Mawayana [nl] people living in ethnic Wai-wai and Tiriyó villages in Brazil, Guyana and Suriname.
[6][2] Aikhenvald (1999) lists Mawayana (and possibly Mawakwa as a dialect) together with Wapishana under a Rio Branco (North-Arawak) branch of the Arawakan family.
Carlin (2006:314) notes that Mawayana "is closely related to Wapishana" and according to Ramirez (2001:530) they share at least 47% of their lexicon.
Mawayana has, among its consonants, two implosives, /ɓ/ and /ɗ/, and what has been described as a "retroflex fricativised rhotic", represented with ⟨rž⟩, that it shares with Wapishana.
