This innovative collection brings together contributions from established and emerging scholars highlighting the "appliability" of Systemic Functional Linguistics and the ways in which theoretical and analytical conclusions drawn from its applications can inform and advance the study of language. The book discusses SFL's theoretical foundations and development in recent years to demonstrate its evolution into a more effective analytical tool. Building on this theoretical framework, the volume showcases the theory's applications in case studies exploring four sub-disciplines of language study: multilingual studies; translation studies; language learning and language teaching; and genre analysis. This all-inclusive volume demonstrates both Systemic Functional Linguistics' efficacy as a means of theoretical analysis, but also its value as a unique approach to the study of language and meaning, making this an indispensable resource for researchers and scholars in applied linguistics, discourse analysis, genre studies, translation studies, and multilingualism.
