FAQ

Questions Merriam-Webster owners ask.

  • 01

    Do I need separate API keys for the dictionary and thesaurus?

    Yes, Merriam-Webster provides separate keys for the Collegiate Dictionary and the Collegiate Thesaurus. You must provide both in the credentials section to enable all capabilities.

  • 02

    What happens if a word is not found?

    If an exact match is not found, the API often returns a list of suggestions. Your agent will display these suggestions to help you find the correct term.

  • 03

    Can I see the part of speech for a word?

    Yes! Every definition returned by the define_word capability includes the part of speech (e.g., noun, verb, adjective) next to the word headword.
