In Chinese, the adverbs 就 (jiù) and 才 (cái) are placed before verbs as adverbials. 就 indicates that the speaker perceives an action as happening early, quickly, or smoothly. In contrast, 才 indicates that the speaker perceives an action as happening late, slowly, or with difficulty. In English, 就 often translates to “already”, “in just”, or “as early as”, while 才 translates to “not until”, “only then”, or “only after”.
Grammar Rules
1. Speaker's Subjective Perception: Both adverbs convey the speaker's subjective view regarding time and efficiency rather than an objective measurement of time.
2. Characteristics of “就”: Emphasizes that an action took less time or occurred earlier than expected. Sentences describing past events using 就 frequently end with the particle 了 (le).
3. Characteristics of “才”: Emphasizes long waits, delays, or difficulty. Sentences using 才 never take a sentence-final 了 (le).
Grammar Structure

Examples
中国银行很近，走路几分钟就能到。
Bank of China is very close, just a few minutes' walk away.
我下午要去医院，很晚才能回来。
I have to go to the hospital this afternoon and will only be able to come back very late.
我早上五点就起床了。
I got up as early as 5 o'clock this morning.
坐火车去北京，五个小时才能到。
Taking the train to Beijing takes five hours (you won't arrive until five hours later).
Important Note
Compare the nuance in meaning:
五点就起床了 (Wǔ diǎn jiù qǐchuáng le) = Got up at 5 o'clock (the speaker considers this remarkably early).
五点才起床 (Wǔ diǎn cái qǐchuáng) = Didn't get up until 5 o'clock (the speaker considers this late).
Common mistake: Adding 了 (le) to the end of a sentence containing 才 is grammatically incorrect (e.g., “五个小时才能到了” is wrong).
