Siwi (or ∂ǧlan n-Isiwan 'the language of the Siwis') is the most easterly Berber language spoken by approximately 20,000 people in the oasis of Sīwa in Western Egypt. The oasis was independent from Egypt until the 19th century but was crossed by an important North-African trade route to Cairo. Hence an enduring heterogeneous influence from individual immigrants (Arabs and other Berbers) and Subsaharan slaves has probably led to the current linguistic state, where some of the 'typical' Berber features in morphology and syntax are missing. The intention of the project, the origin of which goes back to students' field records, was to provide a more thorough phonological basis for its morphosyntactic description since the few existing studies on Siwi have significant shortcomings in this respect. A commitment for collecting oral literature was planned.
