Published last year to mark the 30th anniversary of the first edition, this Collins flagship dictionary has been updated for 2010 to include the very latest words entering the English language. The only dictionary of its kind to be updated every year, Collins English Dictionary is not only comprehensive and authoritative, but also offers outstanding coverage of world, regional and dialect English. Collins English Dictionary is a rich source of words for everyone who loves language. This reissue of the 30th anniversary edition includes the latest words to enter the English language as well as a wide range of biographical entries. Usage notes give advice on using the right word in the right place, and thousands of etymologies trace the roots of modern English. A clear, two-colour page design helps to make this dictionary accessible and easy to use, and the new virtual thumb tab makes it even easier to find the entry you are looking for. This reissue of the dictionary contains an updated supplement on the latest words to enter the language, as well as those 'bubbling under' the surface. Also included is an extended essay on how English has changed in the last 30 years, and looking forwards to the next 30 years. All definitions, examples, idioms, and usage notes are based on the Collins Corpus -- our unrivalled and constantly updated 2.5 billion-word database of today's English -- making it an authoritative and up-to-the-minute reference source.
