Short answer

How can I check word usage and parts of speech with my AI?

Your agent uses the define_word tool to pull real-time data from Merriam-Webster. It provides the exact part of speech and official usage examples to confirm your technical writing is correct. You get precise linguistic validation for every term you query.

The outcomes of a lookup.

Where every check lands.

Every request results in one of these four states.

VALIDATED

Correct terminology

The AI confirms the word matches the official dictionary definition. You get peace of mind that your technical specs use standard English.

REFINED

Better usage examples

The agent pulls real examples of how the word is used in context. You can use these to adjust your own sentence structures.

FLAGGED

Usage errors found

The AI identifies when a word is being used as the wrong part of speech. It highlights these discrepancies so you can fix them before publishing.

HUMAN

Manual review needed

If a term is highly specialized or slang, the AI will tell you it can't find a match. You'll need to step in and verify the term yourself.

The workflow

What your AI does when a term is queried.

The agent handles the heavy lifting of looking up linguistic data.

  1. Identify the term

    Your agent scans your text or your prompt to isolate the specific word you want to check.

    define_word

  2. Fetch dictionary data

    The agent calls the dictionary tool to get the official definition and part of speech.

    define_word

  3. Retrieve usage context

    The agent pulls specific examples from the dictionary to show how the word functions in a sentence.

    define_word

  4. Report findings

    The agent presents the definition, part of speech, and examples directly in your chat interface.

FAQ

How the verification works

  • 01

    Can the AI change my document directly?

    No. The AI only provides the definitions and examples. You must manually apply any changes to your document.

  • 02

    What happens if the word isn't in the dictionary?

    The AI will report that it cannot find a definition. It won't guess or invent a meaning for technical jargon it doesn't recognize.

  • 03

    Does it provide synonyms?

    No. The tool provides definitions and usage examples, not a list of synonyms.

  • 04

    Can I use this for slang or niche jargon?

    The AI only pulls from official Merriam-Webster data. If the term is not in their database, the AI won't be able to verify it.

  • 05

    Will it check my spelling?

    No. The tool is for verifying the meaning and usage of words, not for running a spell check.
