A PRACTICAL COURSE FOR DEVELOPING WRITING SKILLS IN ENGLISH

Today, more than ever before, there is a realization that communicating properly, especially in writing, is essential for all the job aspirants as well as those employees—budding managers and others—eager to build up their career. Taking this scenario into account, this book equips the reader with the ability to learn and enhance the writing skills in English. From fundamentals of grammar to precis, paragraph and essay writing, this book dwells on all aspects of the language besides listing the words (both new and old) to enhance one’s word power, and the foreign words used in the English language. Divided into eight sections, the book describes eight effective tools to master the art of writing. The book begins with the basics of writing, and it then goes to give a careful analysis of functional grammar, vocabulary, common errors committed and their rectifications. Finally, the book showcases the intricacies of formal and informal writings and creative writing to make a learner proficient in these areas. Each section is supported with simple examples, and easy-to-perform Practice Exercises along with their answers. The book is intended for the undergraduate students (both regular and correspondence courses) of all universities, and higher secondary (plus 2) students of all boards. The book will also be beneficial for the students appearing for the competitive examinations and interviews as well as for the general reader who wishes to improve his/her English writing skills.

By and large, the ability to write anything creatively is the ultimate goal of
developing writing skills. It is because it serves the dual purpose. The Inaugural
Ceremony of the Common Wealth Games 2010, held in Delhi is the live example
of it.
