Macmillan English Dictionary for Advanced Learners, also known as MEDAL, was first published in 2002 by Macmillan Education. MEDAL is an advanced learner’s dictionary and shares most of the features of this type of dictionary: it provides definitions in simple language, using a controlled defining vocabulary; most words have example sentences to illustrate how they are typically used; and information is given about how words combine grammatically or in collocations.

In addition to the dictionary, the online version has a thesaurus function enabling users to find synonyms for any word, phrase or meaning. There is also a blog (the Macmillan Dictionary Blog) with daily postings on language issues, especially on global English and language change.
