The Routledge Handbook of Arabic Second Language Acquisition introduces major current approaches in Arabic second language acquisition (SLA) research and offers empirical findings on crucial aspects and issues to do with the learning of Arabic as a foreign language and Arabic SLA. It brings together leading academics in the field to synthesize existing research and develops a new framework for analyzing important topics within Arabic SLA. This handbook will be suitable as a reference work for advanced undergraduate and postgraduate students and scholars actively researching in this area and is primarily relevant to sister disciplines within teacher training and Arabic applied linguistics. The themes and findings should, however, also be attractive to other areas of study, including theoretical linguistics, psycholinguistics, cognition, and cognitive psychology.
