This book is a good companion for teachers and learners of the English grammar. It gives the opportunity for teachers to journey with their students in the teaching and learning of grammar, especially in a non-native English speaking context. It encourages an understanding of grammar through the use of a metalanguage. Learners no longer have to depend on the 'it feels right' defense but can confidently support grammar usage with sound explanation. ESL learners from the secondary school level to tertiary level as well as learners who are preparing to be English teachers will find the aspects and depth of the contents covered in this book useful. The book inculcates the practice of 'awareness, analysis and explanation' which helps learners to tap into the many grammar guides and resources available.
