Twelve relationships: synonyms, antonyms, related concepts (means-like), perfect rhymes, near rhymes, sounds-like, spelled-like, popular adjectives describing the word, nouns the adjective often modifies, triggers (associations), homophones and consonant matches.
Yes. Add one or more comma-separated topics — e.g. music, jazz or medicine — to bias the results toward that domain. Useful for finding synonyms that fit a specific context.
Rhymes match the ending phonemes (cat → bat, hat). Near rhymes loosen that constraint. Sounds-like matches overall phonetic similarity anywhere in the word. Spelled-like matches by letter overlap, not sound.
From the Datamuse API's metadata flags. Definitions come from WordNet; part-of-speech tags use the standard Penn Treebank set (n, v, adj, adv); frequency is the Google Books Ngram count per million words.
Yes — that's exactly what the rhyme, near-rhyme and triggers modes are for. Combine them with topic constraints to find rhymes that match a verse's theme.
Yes. Each result set can be exported as CSV, JSON or plain text. You can also copy each format with one click.
No. The Word Explorer needs an internet connection to query the Datamuse API. Page assets (fonts, libraries) are cached by the HCODX service worker for instant page loads, but the dictionary lookup itself requires a live API call.
