Cobuild new student's dictionary انگلیسی 2002

Like all Collins COBUILD dictionaries, this new second edition of the Student's Dictionary is based on the analysis of real language in use. The words explained in this dictionary account for over 90% of the language that is written and spoken. That is because there is a relatively small number of words which are used over and over again, while there is a large number of words which are not used very frequently. This dictionary concentrates on the words that occur over and over again, and the entries represent the language that students really do need to know and to use. The entries provide a detailed account of the main uses and meanings of each word. Each of the word forms is listed at the start of each entry, along with information about variant spellings where they exist. Explanations are written in full sentences and reflect typical grammatical bahaviour as well as providing a clear description of meaning. Over 3000 of the most frequent English words in the dictionary are clearly labelled with a star. The final section of the dictionary comprises a clear, thorough English Grammar Guide, which explains the rules and principles of the English grammatical system.
