Wiktionary

Wiktionary is a multilingual, web-based project to create a free content dictionary of terms in a large number of natural languages and a number of artificial languages. These entries may contain definitions, images for illustration, pronunciations, etymologies, inflections, usage examples, quotations, related terms, and translations of terms into other languages, among other features. It is collaboratively edited by volunteers via a wiki. Its name is a portmanteau of the words wiki and dictionary. It is available in 198 languages and in Simple English. Like its sister project Wikipedia, Wiktionary is run by the Wikimedia Foundation, and is written collaboratively by volunteers, dubbed "Wiktionarians". Its wiki software, MediaWiki, allows almost anyone with access to the website to create and edit entries.
