Practical English Usage is a dictionary of problem points in the language for foreign learners and their teachers. It answers the learner`s question, `Is this right or wrong, and why?` and the teacher`s question, `How can I explain this to my classes?` It gives information and advice that is practical, clear, reliable and easy to find. Most of the book is about grammar, but it also covers selected points of vocabulary, idiom, style, pronunciation and speling.

For this new edition the text has been thoroughly revised and brought up to date. It is now even more informative, better organised and more clearly presented. Many explanations and examples have been improved or rewritten.
