What Wiktionary does
Wiktionary is a free, multilingual, wiki-based dictionary project operated by the Wikimedia Foundation, a 501(c)(3) non-profit charitable organization headquartered in San Francisco, United States. Launched in 2002, Wiktionary provides word definitions, etymologies, pronunciations, translations, usage examples, and grammatical information across more than 100 language editions, including English (8,838,000+ entries), French (6,930,000+ entries), Malagasy (5,930,000+ entries), Chinese (2,333,000+ entries), Greek, Russian, German, Dutch, Finnish, and Japanese. Each language edition functions as an independent wiki-based dictionary accessible via language-specific subdomains (e.g., en.wiktionary.org, fr.wiktionary.org). The platform is built on MediaWiki, the same open-source wiki engine that powers Wikipedia, and is licensed under Creative Commons Attribution-ShareAlike License 4.0.
The platform is staffed by 7 employees (per firmographic data) and depends on a global community of volunteer editors and contributors who create, edit, and curate dictionary entries. Wiktionary does not generate direct revenue: it is freely accessible to all internet users with no subscriptions, paywalls, advertisements, or premium tiers. Funding flows indirectly through donations and grants to the Wikimedia Foundation, which provides infrastructure, hosting, legal support, and fundraising for the project. The go-to-market motion is entirely community-led and organic — discovery occurs through search engine optimization (Wiktionary ranks highly for dictionary-related queries) and word-of-mouth within language-learning communities.
The user base is horizontal and consumer-facing, with the primary segment being the general public and language learners worldwide seeking free dictionary access. No commercial sales motion exists. Wiktionary has no subsidiaries, no external investors, no venture funding, and operates as part of the broader Wikimedia family of free-knowledge projects alongside Wikipedia, Wikimedia Commons, Wikibooks, Wikidata, Wikivoyage, Wikiquote, Wikisource, Wikispecies, Wikifunctions, and Meta-Wiki.
