The record

Product: Wordnik describes itself as the world's biggest online English dictionary by number of words and says its mission is to find and share as many English words as possible.
Definitions: The site shows definitions from multiple sources, and the API offers definitions from five dictionaries covering more than 800,000 words.
Examples: Wordnik provides real example sentences and links to their sources for more than 10,000,000 words.
Related words: Wordnik's word relationships include synonyms, hypernyms, hyponyms, words used in the same context, reverse dictionary results, and tags.
Other API features: The API includes audio pronunciations, word-of-the-day and random-word endpoints, spelling suggestions, and word phrases.
Community features: Logged-in users can create word lists, comment on word pages, list pages, and profiles, and mark words as favorites.
Integrations and data sources: Wordnik says it uses WordNet for much of its hypernym and hyponym data, and its word-page images come from Flickr under a Creative Commons license.
API use: Wordnik permits commercial apps using its API, but asks commercial apps beyond proof-of-concept stage to upgrade to a paid plan; an app cannot duplicate the Wordnik API itself.
API caching limit: Basic Plan users cannot cache API data; paid-plan users may temporarily cache display text, but not raw API data, for offline use.
Downloadable data: Wordnik offers a downloadable dataset of nearly 200,000 words and definitions optimized for word games.
Security: Wordnik's privacy policy says it uses administrative, physical, and electronic safeguards, including encryption, firewalls, and SSL during transmission, and says it cannot guarantee protection against all threats.
Privacy: Wordnik's FAQ says it will never sell personal user data or share it with other organizations or use it for marketing purposes.
Support: Wordnik directs API questions to [email protected] and general feedback to [email protected].
Company: Wordnik states that it is a 501(c)(3) nonprofit organization; its About page lists a postal address in Portland, Oregon.
