The Wariʼ language (also Orowari, Wari, Pacaá Novo, Pacaás Novos, Pakaa Nova, Pakaásnovos) is the sole remaining vibrant language of the Chapacuran language family of the Brazilian–Bolivian border region of the Amazon. It has about 2,700 speakers, also called Wariʼ, who live along tributaries of the Pacaas Novos river in Western Brazil. The word wariʼ means "we!" in the Wariʼ language and is the term given to the language and tribe by its speakers. Wariʼ is written in Latin script.

There are some sounds not listed which are only used in onomatopoeia and can violate the usual phonotactic and phonological constraints. Consonants The Oro Nao dialect of Wariʼ as described by Everett & Kern (1997) has the following consonant phonemes. It is a relatively large inventory by Lowland Amazonian standards. The angled brackets represent the spellings associated with each sound. is a trilled affricate made up of a bilabial trill preceded by a dental stop, and is only reported from four other languages. In Oro Nao, this has been analysed as an allophone of /t/ that only occurs before /o/ and /y/ which does not occur in every idiolect. In some dialects it is a separate phoneme; however, only about 24 words contain the sound, some of which are onomatopoeic. It also is used more by older speakers of the language. Consonant Alternations /t͡ʃ/ can become , with a tendency to surface as [ʃ] more before unrounded vowels than rounded ones: 'he is thin' can be [t͡ʃaˈt͡ʃiʔ na] or [ʃaˈʃiʔ na]. [m] can become (a sequence of the bilabial nasal followed by the voiced bilabial stop) syllable initially, most frequently before /a/ but also before other vowels. The tendency to realise it as a sequence is greater if the syllable is stressed: its filth can be [homiˈɾi] or [homᵇiˈɾi].
