Look up a word in the Merriam-Webster thesaurus — the authoritative American English thesaurus. Returns synonyms and antonyms grouped by sense, along with part of speech (noun, verb, adjective, etc.) and short definitions. When the word is not found, returns close spelling suggestions instead. Example: thesaurus({ word: “happy” })
Parameters
