The book has been written, in the first instance, for teachers and prospective teachers (TESOL/TEFL) whose first language is not English. A key aim of the book, then, is assisting both students and teachers on a practical level by equipping them with the knowledge and the awareness to answer any challenging questions a teacher or an enquiring student may pose over the course of an English class. It will also prove invaluable to students of all disciplines who seek a better grasp and understanding of English grammar—essential for achieving competency in both writing and reading.
