How to study 必 in context

  1. Say bì, then recall the core meaning: surely, certainly.
  2. Write all 5 strokes while keeping the overlaid balanced.
  3. Use it in 必须 (bì xū), meaning “to have to”.
  4. Read the complete sentence aloud once, then cover the translation and explain how 必 works in that context.

Definitions and traditional forms are compiled from Make Me a Hanzi, HSK curriculum data, and CC-CEDICT. Sourced example sentences link to Tatoeba; editorial examples are labeled separately. Review data sources and licenses.
