Attrition and revival in Awjila Berber

International audience Awjila Berber is a highly endangered Berber variety spoken in the East of Libya. Only minimal material is available on the language. This is unfortunate, as that material reveals that the language is in some respects very archaic and in others grammatically unique, and as such is of particular comparative and historical interest. Fieldwork has been impossible for decades due to the political situation, leading to uncertainty about whether the language was even still spoken. With the rising popularity of Facebook, however, more and more Berber speakers are taking to Facebook to converse in their own language. Several inhabitants of Awjila have accordingly set up a Facebook page Ašal=ənnax "our village" where they communicate with one another in the Awjila language. The authors have collected a corpus of the conversations on this Facebook page, which have been transcribed and translated. Analysis of this corpus adds substantially to our knowledge of Awjili and its situation. The posters' discussion of their motivations for using the language cast light on the language's prospects for survival, while the posts themselves yield many previously unattested words. At the same time, the corpus provides a case study in language contact. Examination of the grammatical and lexical features of this “Facebook-Awjili” language reveals that these speakers' usage is heavily influenced by Arabic, showing extensive language attrition absent from earlier data. The resulting constructions show parallels with other contact-heavy varieties, notably Siwi. In both respects, this study casts light upon the uses and limits of social media as a source of linguistic material.
