Datamuse Hypernyms Lookup

Use this endpoint when you need lexical hypernyms — semantically broader, more general category terms — for a specific English word, especially for NLP enrichment, ontology building, or semantic reasoning tasks. Prefer this over general thesaurus APIs when you specifically need the 'is-a' generalization relationship.

• Missing or empty 'word' parameter returns an error or empty result
• Unknown or misspelled word returns an empty hypernym list
• Word with no known hypernyms in Datamuse returns empty array
• Network timeout or service unavailability returns HTTP error
• Non-English or special-character words may yield no results
