Longman Dictionary of American English 5 Paper & Online (HE)

Longman dictionaries are compiled using the Longman Corpus Network - a huge database of 430 million words of spoken and written English - collected from both British and American English sources. They are easy to use and easy to understand: they are written using a limited vocabulary of just 2000 words - the Longman Defining Vocabulary - ensuring that they all have clear and understandable definitions.
