WordNet is organized by the concept of synonym sets (synsets), groups of words that are roughly synonymous in a given context. The glossary definition and the example sentences are shared among all synonyms in a given synset. (source)Wordnet has definitions to differentiate between senses, not to serve as a completely accurate description of how the word is used, and its idea of what makes words synonyms is very liberal compared to standard dictionaries.
