Practical English Usage

Authors: Michael Swan

Levels: Intermediate to Advanced

Practical English Useage 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 that is 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 spelling.
