Welcome to the English-language Wiktionary, a collaborative project to produce a free-content multilingual dictionary. It aims to describe all words of all languages using definitions and descriptions in English.
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.
It is also the eve of World Meteorological Day, which is recognized by the United Nations to highlight the contribution that national meteorological and hydrological services make to the safety and well-being of society.
This is the English-language Wiktionary, where words from all languages are defined in English. For example, see the entry for the French word dictionnaire. To find a French definition of that word, visit the equivalent page in the French Wiktionary.
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:
