About Dictionary & Language Tools
A dictionary, thesaurus and rhyming dictionary built on Princeton WordNet 3.1 and the CMU Pronouncing Dictionary. Definitions are grouped by part of speech with examples and IPA pronunciation, synonyms and antonyms are grouped by meaning, and rhymes are matched by sound rather than spelling.
The spell checker and grammar checker underline mistakes as you type and fix them in one tap. Lookups use small dictionary files cached by your browser, and your words stay in the address bar after the # sign, so nothing you type is sent to a server.
