Free Dictionary
English word definitions, phonetics and audio as JSON.
Pass a word on the URL and get back an array of entries with definitions, parts of speech, example sentences, synonyms and pronunciation audio links. Keyless and CORS-friendly, drawn from open dictionary data. Individual entries carry their own source licenses (CC BY-SA 4.0 shows up on some).
