Wiktionary is also a thesaurus. Wiktionary is run by the Wikimedia Foundation, which also runs Wikipedia. The English Wiktionary currently has over 7.3 million pages and 4.0 million users. Much like Wikipedia, the Wiktionary is run in several different languages that can be selected from its main page. These include the Simple English Wiktionary.
