Buu is a language spoken by no more than 200 people in Lower Fungom, one of the linguistically most diverse micro-areas of sub-Saharan Africa. This project aims to document Buu from the perspective of the actual communicative practices observed in the village by focusing on three different contexts. This is expected to not only allow me to document, albeit initially, Buu as a distinct language, but also to provide an opportunity to develop best practices to integrate ancestral-code and communicative-practices modes of documentation in one and the same project.
