The first edition of Halliday's Introduction to Functional Grammar Fourth Edition heralded a new way of 'doing grammar' and this innovative approach, in which grammar and discourse are systematically related to one another, quickly became a worldwide phenomenon. This book sets out the principles of functional grammar analysis, engaging with grammar through discourse, using a multitude of examples from translation and the law. More recently, it has begun to be used with other semiotic systems such as drawing and patining, musuic and gesture, and as a model in the description of languages other than English. This fourth edition has been revised in view of the recent new uses of the theory and now focuses on the following features: -The ecology of grammar illustrating systematically how each major system serves to realise a semantic system. -A systematic indexing and classification of examples, using more corpus examples, indicating how the use of the corpus varies according to the register. -Clearer links to related material, offering the opportunity for further study and showing where more original research is needed. Halliday's Introduction to Functional Grammar Fourth Edition is now accompanied by extended textual and audio examples at www.hodderplus.
