Welcome to the English language Wiktionary, a collaborative project to produce a free-content multilingual dictionary.
Designed as the lexical companion to Wikipedia, the encyclopaedia project, Wiktionary 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.
This is the English Wiktionary: it aims to describe all words of all languages using definitions and descriptions in English. For example, see dictionnaire (a French word). In order to find a French definition of that word, you would visit the equivalent page in the French Wiktionary. For more information, see our Multilingual coordination page and Multilingual statistics.
Wiktionary is run by the Wikimedia Foundation, a non-profit foundation headquartered in San Francisco, California, USA. Wikimedia operates several other multilingual and open-content sister wiki projects:
