Most often we are judged by our language and misjudged because of the common errors in our language. A person interacting with you for the first time does mind your language and your language does make a favourable or unfavourable impression on the person and it does account for your success or failure in any attempt you make to achieve something. In fact, no great people of the world would have been great if they had not had the language they had. Unlike other books on common errors, the errors in this book have not been categorized into different chapters based on grammar.
