Character Breakdown

Usage of

The character (wèi) is a formal adverb meaning "not yet." It is commonly used in written and formal spoken Chinese to indicate that an action or event has not occurred up to the present time. Unlike the simpler (bù), which negates present or habitual actions, specifically emphasizes that something has not happened but is expected or possible in the future.

Common Collocations

  • 完成 (wèi wánchéng): not yet completed
  • 开始 (wèi kāishǐ): not yet started
  • (wèi bèi): not been (passive voice)

These collocations are often used in formal contexts such as reports, announcements, or academic writing.

Nuances and Usage Tips

  • is often paired with verbs in perfective or passive constructions to highlight incompletion.
  • It is more formal and literary than (hái méi), which is more common in everyday speech.
  • Avoid confusing with (méi), which negates past actions without the "not yet" implication.

Common Confusion

Learners sometimes confuse with (mò), which means "end" or "final." Remember relates to time and incompletion, while refers to the final part of something.
