Overview

Pass the English word you want to look up, and the endpoint returns a comprehensive entry. The structure is highly dynamic — if a word has no common phrases or synonyms, those fields are simply omitted so the frontend can render leanly.

What's Returned

  • Phonetics & pronunciation (phonetics): UK and US phonetics, plus pronunciation audio URLs you can play directly on the frontend.
  • Chinese definitions (definitions): translations grouped by part of speech.
  • English definitions (english_definitions): native English explanations with short examples.
  • Word forms (word_forms): plural, past tense, comparative, and other inflections.
  • Phrases & synonyms (phrases / synonyms): common collocations and synonyms grouped by part of speech.
  • Bilingual examples (examples): English-Chinese example sentences in real context.
