Intended for post-intermediate students and for students preparing for the Cambridge First Certificate and Proficiency examinations, it is suitable for use in class and/or for self-study. The Wordbuilder represents a vast resource of vocabulary items including collocations and idiomatic expressions not easily retrievable from a standard dictionary. The book is made up of 60 units, each focussing on one vocabulary area. Each unit starts with a reference section, showing words in context, and continues with a practice section of exercises and ideas for further written or spoken practice. The Index contains every word and phrase and an Answer Key gives answers to exercises in the practice section of each unit.
