Cavineña language

Cavineña is an indigenous language spoken on the Amazonian plains of northern Bolivia by over 1,000 Cavineño people. Although Cavineña is still spoken, it is an endangered language. Guillaume states that about 1200 people speak the language, out of a population of around 1700. Nearly all Cavineña are bilingual in Spanish.
The Cavineño people live in several communities near the Beni River, which flows north from the Andes. The nearest towns are Reyes and Riberalta.

For a sentence with a pronominal subject, there are distinct ergative and absolutive forms of the pronouns:

The clitics are ordered so that 3rd person pronouns precede 2nd person pronouns, which precede 1st person pronouns.
