Cambridge International Dictionary of English (CIDE) is a dictionary for learners and users of English as a Foreign Language (intermediate and upwards). Resulting from several years of language research and analysis, CIDE is based on information from the Cambridge Corpus of 100 million words. Entries and examples demonstrate vocabulary, grammar and usage as they are used today. The strictly controlled 2000-word Defining Vocabulary ensures that the language level of the definitions is within the comprehension of the lowest level of student at which CIDE is aimed. Full coverage of international English is given including British, American and Australian varieties. The unique Guide Words act as 'signposts' and help the student distinguish quickly between different senses of the same word. Detailed grammar information is given but complicated grammar codes are avoided.
