Comments for the prior editions - Why is it unique?
The Longman Dictionary of American English is unique because it has been written using the Longman Defining Vocabulary. Other dictionaries use high-level, idiomatic language in their definitions which forces students to look up the defining words as well as the words they're looking up in the first place. Only the Longman Dictionary of American English uses a defining vocabulary made of the 2,000 words that make up the intermediate-level student's most frequent vocabulary.
Longman's lexicographers analyzed the written work of intermediate students of English and the language used in their textbooks. No other dictionary offers definitions written precisely to the needs of intermediate students.
