This volume models how the linguistic description that Systemic Functional Linguistics has developed over decades can indeed be used to address practical problems. Through chapters that take on a diverse range of problems, such as pedagogical issues, illness, and popular texts, it offers an excellent cross-section of work that can guide both novice and experienced researchers who are interested in exploring how powerful linguistics can be as a form of social action. * Priscilla Angela T. Cruz, Department Chair, Department of English, Ateneo de Manila University. Philippines * This book makes a unique contribution to systemic functional theory, documenting its application to different research problems in a rich variety of settings. The contributors include established and emerging scholars, practitioners and scholar-practitioners whose work demonstrates the powerful dialectic of theory, description and practice in action across the globe. -- Pauline Jones, University of Wollongong, Australia
