## Frequently Asked Questions

### Does it show pronunciation and audio for a word?

Yes. `define` returns phonetics, pronunciation audio, parts of speech, meanings, examples, synonyms, and antonyms.

`define` explains the word itself. `synonyms` gives close alternatives, ranked by relevance, which is better for rewriting.

Yes. Use `rhymes` for poetry and songwriting, and `related_words` when you want connected ideas for brainstorming.
