The Collins COBUILD Advanced (Learner's) Dictionary is now in its 6th edition from HarperCollins Publishers. Over the years, from the 1st to 6th edition, the number of references increased slightly from over 60,000 to 75,000+, and of examples - from 90,000 to 105,000. The definitions are full sentences very easy to understand and not just phrases. The words have phonetic transcriptions, except in the 6th edition, based on the most popular phonetic alphabet IPA. Plentiful example sentences show how to use the words.
The 3rd edition of 2001 introduced a digital version on CD-ROM included with the book on paper. That 1st digital version apparently had more examples than the latter ones (Google: Review of the Collins COBUILD Advanced Learner's English Dictionary). The equivalent for American English buffs is titled Collins COBUILD Advanced Dictionary of American English.
