This present book studies from a dialectological perspective various African Arabic varieties, such as Maghreb Arabic, Bongor Arabic, Juba Arabic and Logor├н Arabic. On the one hand, different specific linguistic aspects related to phonetics and phonology as well as to morphology, syntax and lexicology are discussed in this volume; e.g. the Arabic loanwords in Somali with regard to the strata in South Arabian, the structural features of Logor├м Arabic and its use as Lingua Franca or native language, the contact-induced innovation processes in North African Arabic negation by analogy with Berber negation. On the other hand, the African Arabic theme is approached from a more general perspective analysing the contact effects on linguistic features and systems from a broader comparative, typological and universal viewpoint, e.g. a general typology of Arabic in Africa, the question of possible universal features of pidginization and creolization drawn on evidence from Arabic-based pidgins and creoles. Its outcomes offer important insights for all linguistic studies and approaches, and directly connect with other research fields such as sociolinguistics, ethnolinguistics and language acquisition.
