Mura is a language ofAmazonas, Brazil. It is most famous forPirahã, its sole surviving dialect. Linguistically, it is typified byagglutinativity, a very smallphoneme inventory (around 11 compared to around 44 in English),whistled speech, the use oftone, and a very limited, perception-basednumeralsystem. In the 19th century, there were an estimated 30,000–60,000 Mura speakers. It is now spoken by only 300 Pirahã people in eight villages.

Mura is often proposed to be related toMatanawí.^{[by whom?]} Kaufman (1994) also suggests a connection withHuarpe in hisMacro-Warpean proposal.

Since at least Barboza Rodrigues (1892), there have been three ethnic names commonly listed as dialects of Mura, or even as Muran languages.^[2] The names are:^[3]

• Bohurá, orBuxwaray, the original form of the name 'Mura'; spoken on theAutaz River^[4]
• Pirahã, orPirahá, Pirahán, the name the remaining dialect goes by
• Yahahí, also spelledJahahi; spoken on theBranco River (unattested)^[4]

On the basis of a minuscule amount of data, it would appear that Bohurá (Mura proper) wasmutually intelligible with Pirahã; however, for Yahahí there exists only ethnographic information, and it can be assumed they spoke the same language as other Mura.Rodrigues describes the Yahahí as having come from the Branco river, a tributary of the right bank of the upperMarmelos river. The last Yahahí are said to have joined the Pirahã.^[5]

The Mura/Bohurá endonym isBuhuraen, according to Barboza Rodrigues (1892),^[5] orBuxivaray ~Buxwarahay, according to Tastevin (1923).^[5] This was pronouncedMurá by their neighbors, theTorá andMatanawi. In his vocabulary, Rodrigues listsBohura for the people andbhũrai-ada "Mura language" for the language, from the Mura of the Manicoré River; Tastevin hasBohurai andbohuarai-arasé for the same.^[5] They also record,^[5]
