Irántxe (Irántxe, Iranxe, Iranshe) /iˈɻɑːntʃeɪ/, also known as Mỹky (Münkü) or still as Irántxe-Münkü, is an indigenous language spoken by the Irántxe (Iránxe, Iranche, Manoki, Munku) and Mỹky (Mynky, Münkü, Munku, Menku, Kenku, Myy) peoples in the state of Mato Grosso in Brazil. Recent descriptions of the language analyze it as a language isolate, in that it "bears no similarity with other language families" (Arruda 2003). Monserrat (2010) is a well-reviewed grammar of the language.
Vitality and dialects
According to the UNESCOAtlas of the World's Languages in Danger, Irántxe-Mỹky is currently not thriving. While the Mỹky dialect is considered "vulnerable", the Irántxe variety is deemed "considerably endangered", with only 10 fluent speakers out of the 356 ethnic Irántxe-Mỹky in the 2006 report. As of 2011, the 280 Irántxe have largely assimilated to Brazilian culture. Most are monolingual in Portuguese, and the remaining Irántxe speakers are over 50 years old. A splinter group, the Mỹky, however, moved to escape assimilation, and were isolated until 1971. As of 2011, there were 80 ethnic Mỹky, all of whom spoke the language.
An automated computational analysis (ASJP 4) by Müller et al. (2013)[4] also found lexical similarities between Irántxe-Mỹky and Nambikwaran.

Consonants
Irántxe-Mỹky has a small consonant inventory. Voicing is not contrastive for any consonant. In the Monserrat analysis shown in the table, there is a series of palatalized stops /pʲ tʲ kʲ/ and nasals /mʲ nʲ/, which reviewer D’Angelis (2011) analyzes as /Cj/ sequences. In Monserrat's analysis, /ʃ/ is a separate phoneme from /sʲ/.
The bilabial /m/ may occur as [mb] word initially, especially among the Irántxe: muhu [mbuhu], mjehy [mbʲɛhɨ].
The sibilant /s/ is pronounced [ʃ] before /j/.
The trill /r/ may also occur as [l].
The palatal approximant /j/ occurs as [ɲ] before nasal vowels.
Vowels
The vowel inventory of Irántxe-Mỹky is large, with 21 phonemic vowels. Vowel length and nasalization are contrastive in the language. The role of tone is not clear.
Loukotka (1968) lists the following basic vocabulary items for the Irántxe dialect,[6] later expanded in Holanda's (1960) larger vocabulary list.[7] The Mỹky words derive from the dictionary compiled by Monserrat.[2]
