This is the second edition of An Introduction to Systemic FunctionalLinguistics first published in 1994. The book offers a comprehensive overview of systemic theory and demonstrates how systemic techniques can be applied in the analysis of texts. Written for students who have little or no formal knowledge of linguistics, it covers the major concepts in systemic linguistics including semiotic systems, genre, register, text, cohesion and grammatical metaphor. Using the influential work of M. A. K. Halliday as a foundation, the book also presents a functional grammatical description of the simultaneous metafunctional organisation of the clause; its Mood, Transitivity, Theme and Clause Complex systems. The basic techniques for analysing cohesive patterns in text, such as reference, lexical cohesion and conjunction, are also introduced. The new edition has been fully updated and includes two new chapters on clause systems and the analysis of what constitutes a text. The new edition has also been enlarged and has improved chapter breakdowns to help students to navigate the book. Lists of texts, systems, figures and tables have also been added, to enable the reader to access examples easily. This comprehensive book is an invaluable resource for students who are new to systemic functional linguistics.
