What Wiktionary is
Wiktionary is a collaborative, free-content multilingual dictionary that users can edit. Entries may provide definitions, etymologies, pronunciations, sample quotations, synonyms, antonyms, and translations. The project also includes a thesaurus, rhyme guide, phrase books, language statistics, and appendices. Its English-language main page lists 10,409,468 entries with English definitions from over 5,200 languages, and the portal links to editions in 181 languages. Volunteer editors write entries, and terms generally need evidence of sufficiently widespread use to qualify for inclusion. Wiktionary describes how words are used rather than prescribing acceptable usage. Content is dual-licensed under Creative Commons Attribution-ShareAlike 4.0 International and the GNU Free Documentation License. The service is free and available on the web, with an API platform listed. Wikimedia wikis expose a MediaWiki Action API endpoint following the /w/api.php pattern.
