Ayoreo [ayo] is a Zamucoan language with approximately 4,000 speakers in Bolivia and 2,600 speakers in Paraguay. The language remains underdescribed, specially the Paraguayan varieties. This project will initiate a documentation of the Ayoreo spoken in Campo Loro, Paraguay by recording and annotating a range of culturally significant text materials in collaboration with the community. The main outcome will be completion of my doctoral thesis, which will include an Ayoreo sketch grammar with a detailed analysis of its clause structure and the production of materials for community use.
