Collins COBUILD Advanced Dictionary
First edition

The Collins COBUILD Advanced Dictionary[1] (CCAD) from HarperCollins, first published in 1987,[2] is a dictionary that distinguished itself by providing definitions in full sentences, rather than excerpted phrases. Example sentences are given for almost every meaning of every word, drawn from a large corpus of actual usage.

Except for the 6th edition, it included phonetic transcriptions based on the International Phonetic Alphabet (IPA). In some editions, a digital version on CD-ROM was included with the dictionary in book form.

The CCAD seems to be lacking in American English definitions. However, it has an American English equivalent titled Collins COBUILD Advanced Dictionary of American English, which was published in 2006 (2nd edition in 2016, 3rd edition 2023).[3]
