An Introduction to Applied Linguistics offers a comprehensive and authoritative overview of the field. Divided into three sections, the book explores a description of language and language use, essential areas of inquiry, and language skills and assessment. The third edition includes an introductory chapter that introduces key issues and recurring themes, followed by 17 extended surveys on central elements of applied linguistics. Two new chapters delve into multilingualism and forensic linguistics, while previously existing chapters have been re-written to cover psycholinguistics, language learners, reading, and assessment. Each chapter features hands-on activities and further reading sections, promoting practical analysis and broader knowledge. Co-edited by two leading international experts, the book is designed for students of applied linguistics, TESOL, and second language pedagogy, as well as practicing teachers and researchers looking to update their understanding.
