This highly accessible, up-to-date introduction provides an overview of critical applied linguistics through an intersectionality framework. The book reflects recent developments through a discussion and evaluation of key questions, diverse perspectives, and practices for social change. As it unpacks different forms of marginalization and privilege, it relates them to language use, critical pedagogies, and critical intersectional advocacy in applied linguistics. A source of reference for all applied linguists; undergraduate/graduate students in applied linguistics, TESOL, and other relevant programs; classroom teachers; and language teacher educators, the book aims to foster critical reflection, critical thinking, and intersectional advocacy. Examples, suggested readings, discussion questions, and questions for reflection not only help personalize the content but also enable the reader to further understand what motivates research, critical practice, and social action in critical applied linguistics.
