English has emerged as the leading language for write-ups, conversations, media and communication. English skills are generally considered a passport to success as they open floodgates of opportunities for the person who acquires them. Grammar is the base on which the correct structure of sentences is laid. The book encapsulates adequate description, apt explanation and scientific presentation of all the major aspects of English grammar. The grammar aims to describe the ways a language should be used to fulfill the communicative needs. This has been taken care of in the book. In addition, attempt has been made to explain the role of various constituents of grammar and their underlying patterns that form acceptable grammar structures. Apart from explaining the usage of parts of speech like noun, pronoun, adjective, verb, adverb, preposition, conjunction, article, etc. other important aspects of core grammar like sentence, time and tense, subject-verb agreement, voice, and narration have also been dealt with. Exclusive chapters have been devoted to punctuation and idioms and phrases. Since writing is an integral part of English skills, paragraph writing, precis writing, and letter writing have been included in the book, besides reading comprehension which is another important English skill. Latest trends in these areas have been given to keep the readers up-to-date. Another important feature of the book is the inclusion of a large number of examples and exercises for easy comprehension by the readers. The book is meant for all those who are interested in developing a competence in English in all possible ways, viz. language skills, pedagogy, grammatical operations, and writing skills. It has been designed to suit the needs of learners as well as teachers.
