The present volume is designed as a workbook for advanced learners of English as a second or foreign language which will train them through instruction and exercises to use an all-English dictionary. The contents are based on the second edition of Hornby, Gatenby, and Wakefield's "The Advanced Learner's Dictionary of Current English," 1963, Oxford University Press. Sections cover the identification of a word according to its class and function; verb forms, their meanings and usage; other parts of speech; collocations, idiomatic word groups, and compounds. Various types of dictionary entries are dealt with, and detailed instructions in the actual use of a dictionary are given. Numerous examples and exercises are provided; answers are appended. (AMM)
