Siwa and its significance for Arabic dialectology

International audienceSiwi is best known for being the easternmost Berber language, but includes a very substantial Arabic stratum. The q reflex of qāf and the final ʾimāla of -ā to -ī in loanwords alone suffice to establish that most of this influence derives neither from Bedouin dialects nor from the main Nile Valley dialects; instead, these link Siwa to other Egyptian oases. Some borrowed grammatical elements, notably lā "not" and qət ̣t ̣"ever", the actor noun formation a-CəCCēCī, and demonstrative agreement with the addressee, underline Siwi’s archaism relative to almost all modern Arabic dialects. The depth of Arabic influence on Siwi suggests very close social contact, and historical sources indicate an Arab presence in the oasis alongside Berber in the 12th century. The Arabic element of Siwi thus provides a new source of evidence on sedentary Arabic dialects that reached the region independently of the Banī Sulaym and probably prior to their 11th century arrival
