Wiktionary (UK: /ˈwɪkʃənəri/ ^ⓘ, WIK-shə-nər-ee; US: /ˈwɪkʃənɛri/ ^ⓘ, WIK-shə-nerr-ee; rhyming with "dictionary") is a multilingual, web-based project to create a free content dictionary of terms (including words, phrases, proverbs, linguistic reconstructions, etc.) in all natural languages and in 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 via a wiki. Its name is a portmanteau of the words wiki and dictionary. It is available in 195 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.

Because Wiktionary is not limited by print space considerations, most of Wiktionary's language editions provide definitions and translations of terms from many languages, and some editions offer additional information typically found in thesauri.

Wiktionary's data is frequently used in various natural language processing tasks.
