Tinigua [ISO 639-3: tit] is the last surviving member of an independent South American Tiniguan family whose other (two?) members have disappeared without substantial documentation; with only one remaining speaker, it is now critically endangered. Additionally, the language is seriously underdocumented and underdescribed. This project aims to provide a linguistic documentation of Tinigua through work with Sixto Muñoz, its last remaining speaker. The expected outcomes of this project are a transcribed, translated and annotated audio-visual corpus of the language, a grammatical description, and a lexicon. Additionally, I aim to gather further historical and cultural data on the Tiniguan culture. Primary investigator: Katherine Bolaños
