The chapters in this book call attention to vulnerabilities, challenges and risks for applied linguistics researchers and the communities they work with across a broad range of contexts from the Global North and South, and in both signed and spoken languages. Together they provide insights on both academic and professional practice across several areas: the vulnerabilities involved in researching, the limitations of traditional epistemologies, the challenges inherent in the repertoire of methodologies and pedagogies employed by applied linguists, and the effectiveness of practical responses to language-related problems. The book encourages those involved in applied linguistics to consider their own practice and their relationship with the communities, policies and educational contexts they engage with in the course of their teaching, research and activism.
