A Communicative Grammar of English has long been established as a grammar innovative in approach, reliable in coverage, and clear in its explanations. This fully revised and redesigned third edition provides up-to-date and accessible help to teachers, advanced learners and undergraduate students of English. Part One looks at the way English grammar varies in different types of English, such as ‘formal’ and ‘informal’, ‘spoken’ and ‘written’; Part Two focuses on the uses of grammar rather than on grammatical structure and Part Three provides a handy alphabetically arranged guide to English grammar. A new workbook, The Communicative Grammar of English Workbook also accompanies this edition.
It's more of a reference book than a book to read through, but the explanations are clear and the examples generally useful. Back in 1975, when it was first published, it was probably a godsend. The third edition incorporates some corpus data, which keeps this book relevant today.
