未 is a formal negation adverb meaning "not yet" or "have not." It functions as the literary equivalent of 没有 and is used extensively in formal writing, legal documents, news reports, and classical expressions.

未 negates completed or expected actions, implying that something has not happened up to the present moment. It is distinct from 不 (which negates habitual actions or intentions). Common collocations include 未曾 (never), 未必 (not necessarily), 未免 (rather / a bit too), and 未来 (future — literally "not yet come").

Podcast: Not Yet in Formal Chinese: 未 (否定副词:未)

Listen to Jason & Amy explain the 否定副词:未 pattern

Understanding 否定副词:未

The negation adverb 未 is one of the pillars of formal Chinese negation. Where spoken Chinese uses 没有 to mean "not yet" or "have not," written Chinese uses 未 for conciseness and elegance. This single character packs the meaning of two syllables (没有) into one, making it perfect for tight, formal prose. You will encounter 未 everywhere in Chinese officialdom, journalism, law, and literature. It also forms the basis of important compound words: 未来 (future), 未曾 (never), 未必 (not necessarily), 前所未有 (unprecedented). Understanding 未 is essential not just for reading comprehension but also for appreciating how Classical Chinese continues to shape the modern language. Every time someone says 未来 or 未必, they are using a word built on this classical negation.

Key Points

  • 未 means "not yet / have not" — the formal written equivalent of 没有.
  • It negates past or expected actions, not habitual ones (that is the role of 不).
  • Extremely common in news, legal documents, academic writing, and formal reports.
  • Key compounds: 未来 (future), 未曾 (never), 未必 (not necessarily), 未免 (rather/somewhat).
  • The expression 前所未有 (unprecedented) uses 未 in its classical sense.
  • Can combine with 尚 to form 尚未 (still not yet) for extra formal emphasis.

The word 未来 (future) literally means "not yet come" — a beautiful example of how Classical Chinese thinking shaped modern vocabulary. Similarly, 未知 (unknown) means "not yet known." These compounds reveal a worldview where the future and the unknown are defined by what has not yet arrived or been discovered.

未 negates completed or expected actions (like 没有), not habitual states or preferences. For negating likes and habits, use 不.

他未去学校。(casual context)
他没去学校。

未 is a formal written word. In casual speech about daily activities, use 没 or 没有. Using 未 in conversation sounds overly stiff.

这件事未不重要。
这件事并非不重要。

未 and 不 serve different functions and cannot stack like this. 未 negates "have/has done," while 不 negates states. For "not unimportant," use 并非不.
