Ayoreo language
Ayoreo is a Zamucoan language spoken in both Paraguay and Bolivia. It is also known as Morotoco, Moro, Ayoweo, Ayoré, and Pyeta Yovai. However, the name "Ayoreo" is more common in Bolivia, and "Morotoco" in Paraguay. It is spoken by Ayoreo, an indigenous ethnic group traditionally living on a combined hunter-gatherer and farming lifestyle. Classification
Ayoreo is classified as a Zamucoan language, along with Chamacoco. Extinct Guarañoca may have been a dialect. Geographic distribution
Ayoreo is spoken in both Paraguay and Bolivia, with 3,100 speakers total, 1700 of those in Paraguay and 1,400 in Bolivia. Within Paraguay, Ayoreo is spoken in the Chaco Department and the northern parts of the Alto Paraguay Department. In Bolivia, it is spoken in the Cordillera Province, in the Santa Cruz Department. Phonology
Bertinetto (2009) reports that Ayoreo has the 5 vowels /a, e, i, o, u/, which appear both as oral and nasal. /j/ can also be heard as [dʒ]. Grammar

When the verb root contains a nasal, there are nasalized variants of the agreement affixes:

Ayoreo is a mood-prominent language. Nouns can be divided into possessable and non-possessable; possessor agreement is expressed through a prefixation. The syntax of Ayoreo is characterized by the presence of para-hypotactical structures. Notes
