Synopsis Proper knowledge of English usage is a great requirement for all those who are desirous to be successful in life. Besides, for all those people who are in need of work or assignments in companies, agencies or other places, this knowledge is of utmost importance. English is mostly considered as an important medium of communication. It is, therefore, imperative to learn its correct usage. It has been observed that students often get confused while writing or speaking certain words of English that have either almost identical spellings or pronunciation. For example, words like `all ready` and `already`, which have almost quite identical spellings and also pronunciation, are often misused. It is, therefore, necessary to learn the correct usage of language to avoid any confusion. Correct usage simply means to be precise and accurate in your expression without creating confusion in the listeners` minds. This book will guide and enrich the students at senior secondary, under-graduate and graduate levels, as well as help all other readers in many ways to improve their language, if they go through it seriously.
