WordNet is a lexical database of the English language containing about 150,000 words organized in over 115,000 synsets for a total of 207,000 word-sense pairs. It groups English nouns, verbs, adjectives and adverbs into sets of cognitive synonyms called synsets each expressing a distinct concept. WordNet provides short, general definitions, and records conceptual-semantic and lexical relations between these synonym sets. The resulting network of meaningfully related words and concepts is a combination of dictionary and thesaurus that is more intuitively usable than traditional dictionaries.
This Kindle edition is a fully functional dictionary and thesaurus and can be installed as a default dictionary on the Kindle.
