Dictionaries are one of the most widely available, but under utilised resources English teachers and students have. Jon Wright's book sets out to rectify that. It is full of practical classroom uses for dictionaries. In fact, there are 98 different exercises with extensions to many. It has techniques for using dictionaries as a learning resource for pronunciation, spelling, vocabulary, reading skills and more. The exercises are photocopiable and so teacher friendly. Although example texts are given in the latter part of the book the exercises are easily adaptable to any texts that appeal to your students. I use this book more often than any other single ELT resource book. I highly recommend it to ELT teachers.
