"Overall, the book is an excellent reference for pre- and in-service language teachers, as well as those interested in the basics of idioms and language teaching. The accessible language, the quick summary and discussion questions that follow each chapter, the glossary, and the annotated list of selective idiom references make this book especially attractive for graduate courses in applied linguistics and related fields."--Teachers College Record "The book draws on a lot of research, is friendly to the reader, and will be of good value to teachers." --Paul Nation, Victoria University of Wellington, Australia
