Wiktionary is a collaborative dictionary and thesaurus designed as the lexical companion to Wikipedia, the encyclopedia project. Wiktionary has grown beyond a standard dictionary and now includes a thesaurus, a rhyme guide, phrase books, language statistics and extensive appendices. Wiktionary aims to include not only the definition of a word, but also enough information to really understand it. Thus etymologies, pronunciations, sample quotations, synonyms, antonyms and translations are included.
