Nalu is an endangered Atlantic language spoken on the littorals of Guinea and Guinea-Bissau. In Guinea, most Nalu speakers live north of the river Nuñez on the Tristão islands, located in the sub-prefecture of Kanfarandé, prefecture of Boké. Across the border in Guinea-Bissau, speakers of Nalu inhabit the Cacine estuary in the Tombali region. Nalu is predominantly spoken by an adult population (>30 years) and counts significantly less than 22,000 speakers. Frank Seidel, ELDP grantee created a record of this little studied and little known group of people. He is producing a dictionary, annotated audio and audiovisual data of texts from different genres, cultural activities etc., six short documentary films, an orthography, and a grammatical sketch.
