Comparing "cai" and "jiu"

Both 才 (cái) and 就 (jiù) are adverbs that have to do with expressing time, and they are both placed in front of the verb. However, they have opposite effects on the tone of the sentence, with 才 (cái) implying a sense of lateness, and 就 (jiù) imparting a sense of earliness.

Emphasis with 才

Expressing Lateness with "cai"

才 indicates that the speaker feels that the events discussed happened later than expected. Sometimes it also expresses anxiety, impatience, anger, or other related emotions.

Structure

Subj. + Time Word + 才 + Verb

Examples

• 我 等 了 两 个 小时 才 买到 票。 Wǒ děng le liǎng gè xiǎoshí cái mǎi dào piào.I had waited two hours before buying the ticket.
• 老板 十一 点 才 到 办公室。 Lǎobǎn shíyī diǎn cái dào bàngōngshì.The boss didn't come to the office until 11 o'clock.
• 这个 项目 最少 要 花 两 个 月 才 能 做 完。Zhège xiàngmù zuì shǎo yào huā liǎng gè yuè cái néng zuò wán.It's going to take at least two months to complete this project.

Expressing Small Quantity with "cai"

才 can also mean "only" in the sense of a small quantity.

Structure

才 ( + Verb) + Measure Word + Noun

Examples

Expressing "Not Late" with 才 and Time

When 才 is followed by a time, it can express the idea of "only," as in, "it's only 9 o'clock," expressing the idea that "9 o'clock is not late." This would seem to be the opposite of the 才 expressing "lateness," but it's important to remember that this 才 precedes a time, and not an action.

• 现在 才 九点 ，再 玩 一会儿 。Xiànzài cái jiǔ diǎn, zài wán yīhuìr.It's only nine o'clock. Stay and hang out a little bit more.

Emphasis with 就

Used to Express Earliness

就 indicates that something has occurred earlier than the speaker expected. There may be an accompanying feeling of surprise or amazement.

Using 才 and 就 Together

They're not matter and anti-matter; these two "opposite" words can actually be used together. When used together, they're the "just recently" meaning of 才 and the "early" meaning of 就. Together, they indicate that one thing just happened recently, and then the other happened soon after.

"才"表示动作在说话前不久发生，有" 刚、刚刚"的意思。常常跟"就"连用，形容某事发生得很快。
