This book highlights the evolution of John Sinclair’s theories and insights from studies on language teaching through detailed analyses of text and discourse, and into his later works on corpus stylistics. More specifically, Part I focuses on how theory can inform teaching practice. Part II is more directed towards linguistic analyses of specific texts and provides practical bases for stylistic approaches. In Part III, Sinclair’s contributions to discourse analysis shed light on ways of looking and understanding literature. This book demonstrates Sinclair’s explicit concern for more systematic approaches to the integration of language and literature and shows why his works on stylistics have been both reference and inspiration to students, language and literature teachers and researchers over many decades.
