Exploring the relationship between theory and practice in Systemic Functional Linguistics (SFL), this volume offers a state-of-the-art overview of Appliable Linguistics. Featuring both internationally-renowned scholars and rising stars from Argentina, Australia, Austria, Brazil, Chile, Denmark, Indonesia, New Zealand, Singapore and the USA, Appliable Linguistics and Social Semiotics examines the theoretical insights, questions, and developments that have emerged from the application of Systemic Functional theory to a range of fields. Beyond simply reporting on the application of SFL to particular sites of communication, both linguistic and semiotic, this volume demonstrates how SFL has critiqued, developed and transformed theory and practice and foregrounds the implications of application for Systemic Functional theory itself. Covering established fields for application, such as education, medicine and media, to relatively uncharted areas, such as software design and extremist propaganda, this volume provides an overview of recent linguistic and semiotic innovations informed by SFL and examines the advances that have been made from many years of productive dialogue between theory and practice.
