Kotiria (Wanano) and Wa'ikhana (Piratapuyo) are two closely related Eastern Tukanoan languages spoken in north-western Amazonia. The project is designed to be both highly participatory—with indigenous research teams trained in documentation methods, manipulation of archival materials, and basic linguistic analysis—and interdisciplinary, focusing on a broad range of themes. Expected outcomes include the consolidation of orthographies, elaboration of materials for indigenous schools, collections of texts in both languages, and a body of annotated data for a reference grammar of Wa'ikhana. Documentation will be closely linked to indigenous education programs and other language and cultural maintenance efforts. Primary investigator: Kristine Stenzel
