Kokama-Kokamilla is a deeply endangered language spoken in the Peruvian Amazon. The need for documentation is urgent as nearly all of the estimated 1500 remaining speakers are elderly people, and natural processes of language transmission have been interrupted. This project involves a significant fieldwork component leading to a comprehensive grammar, a lexicon and collection of texts and video and audio recordings, which will contribute to ongoing language revitalization efforts. The grammar will include substantial analysis of discourse aspects, as well as a historical account for grammaticalization phenomena shedding light on the evolution of the language, and potentially on the history of this people.
