才 (only after)

• Pinyin: cái
• Formation: Condition / Time，才 + Result

Meaning

The adverb 才 placed before a verb indicates that something happened later than expected, or only after a certain condition was met. It conveys the meaning 'not until' or 'only then,' emphasizing delay, difficulty, or a prerequisite.

才 carries a strong implication of lateness or difficulty — the speaker considers the action or result to have taken longer than expected or to have required more effort. This contrasts directly with 就, which implies that something happened sooner or more easily than expected. A common pair is: 他八点才来 (he didn't come until 8 — late) vs. 他八点就来了 (he came as early as 8 — early). Importantly, 才 resists the sentence-final change-of-state 了 because it inherently points to a time relationship rather than a new state. However, verb-suffix 了 (completion) can still follow the verb after 才 in some contexts.

Examples

1. 他等了两个小时，公交车才来。 He waited two hours before the bus finally came.
2. 我复习了很久，才通过了那次考试。 I reviewed for a long time before I passed that exam.
3. 雨停了以后，我们才出发。 Only after the rain stopped did we set off.
