Advanced English Dictionary is distinguished from the other (paper, electronic) dictionaries in many ways. Not because it contains far more words than a conventional paper dictionary, but because it uses a radically new approach and technology called WordNet. Instead of just listing the words and their definitions, Advanced English Dictionary shows how every word is linked to another. Type in the word "tree" and you will get not only the definition, synonyms and opposites, but the hypernyms (a tree is a kind of what?), meronyms (what are the parts of a tree?) and more. You can also find a list of hundreds of trees, from yellowwood to the Tree of Knowledge, and even all words that contain the letters t-r-e-e. This WordNet approach will help you to understand the meanings of words better. Linguists call WordNet project one of the biggest leaps for dictionaries since scholars sat down to write the epic Oxford English Dictionary.
