It is a refresher, a reference book and a workbook for teachers of English. It is also for teachers handling subjects other than English in schools and colleges. The book centres round the idea that grammar paves the way for smooth and accurate communication, and aims to strike a balance between conventional concepts and latter-day developments, and between descriptive grammar and grammar in use. Each chapter of the book begins by describing the forms of the grammatical class or category it deals with. It then presents a variety of illustrative examples. Finally, it explains the communicative uses of the forms and the situations in which they are typically used. A distinct feature of the book is that it deals with both spoken and written grammar, with greater emphasis on the written mode.
