才 (lateness)

• Pinyin: cái
• Formation: Subject + Time + 才 + Verb (+ Object)

Meaning

The particle 才 is used before a verb to indicate that something happened later than expected. It conveys a sense of delay or that the action occurred only after a long wait.

才 emphasizes that the speaker considers the timing to be late or slow. It often appears after a time expression and implies impatience, surprise, or dissatisfaction with the delay. This is in contrast to 就, which indicates something happened sooner than expected. When using 才, the sentence usually does not take 了 at the end, because 才 focuses on the lateness of the action rather than its completion. Common time expressions paired with 才 include specific clock times, ages, or durations that the speaker considers overdue.

Examples

1. 他十点才起床。 He didn't get up until ten o'clock.
2. 我等了两个小时她才来。 I waited for two hours before she finally came.
3. 弟弟十二岁才学会游泳。 My younger brother didn't learn to swim until he was twelve.

Do Say

• 公交车晚点了，我九点才到公司。
• 他想了半天才回答这个问题。
• 排了很长的队，我们才买到票。

Don't Say

• 他十点才起床了。(才 sentences typically do not end with 了 — 才 emphasizes lateness rather than completion) → 他十点才起床。
• 我才八点到了学校。(The time word must come before 才, not after it — place the time between the subject and 才) → 我八点才到学校。
• 她才很晚回家。(Do not use 很 with 才 — 才 already implies lateness, so adding 很晚 is redundant and unnatural) → 她很晚才回家。

Origin & History

才 originally meant 'talent' or 'ability.' Its grammatical use as an adverb meaning 'only then' or 'not until' developed during the medieval Chinese period, conveying the idea that something was achieved with difficulty or after delay.
