## When to prefer this

Use this endpoint when you need to discover what a word or concept is made up of (holonyms) — for example, to build semantic graphs, answer 'what are the parts of X' questions, enrich NLP pipelines with lexical structure, or explore ontological part-whole relationships. Prefer this over general dictionary APIs when you specifically need part-of / composed-of semantic relationships rather than definitions or synonyms.

## Known failure modes

- Missing word parameter returns an error or empty result
- Word not found in Datamuse database returns empty holonyms array
- Non-noun words may return no results since holonymy applies primarily to nouns
- Network timeout if upstream Datamuse API is unavailable
- Invalid query string format may return 400-level error

Things that a given word is composed of / comprises (param: word). Query: ?word= Returns JSON.
