Wiktionary is a collaborative project to produce a free-content multilingual dictionary. It has grown beyond a standard dictionary and now includes a thesaurus, a rhyme guide, phrase books, language statistics and extensive appendices. We aim 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.
Onelook.com allows you to search hundreds of online dictionaries. Think of this web site as a search engine for words and phrases. It also allows you to use wildcards.
