## When to prefer this

Choose this endpoint when you need a comprehensive, structured dictionary entry for an English word — especially when IPA pronunciation, usage examples, synonyms, or antonyms are required. It is ideal for writing assistance, vocabulary education, word games, or language learning tasks. Prefer it over a general web search when structured lexical data (parts of speech, definitions, synonyms) is needed rather than conversational explanations.

## Known failure modes

- Word not found in Wiktionary — returns an error or empty result for rare, archaic, or misspelled words
- Ambiguous or multi-language words may return only the English entry unless a language code is specified
- Audio pronunciation may be unavailable for less common words
- Very new slang or neologisms may not yet be indexed in Wiktionary
