Arabic, one of the official languages of the United Nations, is spoken by more than half a billion people around the world and is of increasing importance in today's political and economic spheres. The study of the Arabic language has a long and rich history: earliest grammatical accounts date from the 8th century and include full syntactic, morphological, and phonological analyses of the vernaculars and of Classical Arabic. In recent years the academic study of Arabic has become increasingly sophisticated and broad. This state-of-the-art volume presents the most recent research in Arabic linguistics from a theoretical point of view, including computational linguistics, syntax, semantics, and historical linguistics. It also covers sociolinguistics, applied linguistics, and discourse analysis by looking at issues such as gender, urbanization, and language ideology. Underlying themes include the changing and evolving attitudes of speakers of Arabic and theoretical approaches to linguistic variation in the Middle East.
