English speakers often translate "not until" by reaching for a negative construction. Mandarin does it differently: you place 才 (cái) between a time and a verb to show that something happened later than expected. In this HSK 2 speaking lesson, you'll practice that pattern in a live voice conversation with AI teacher Mei Lin.
Use 才 (cái) between a time and a verb to signal lateness — the Chinese way to say "not until." Take the example:
昨晚十二点才睡觉 (zuówǎn shí'èr diǎn cái shuìjiào) — "I didn't go to sleep until 12 last night."
The time phrase 十二点 ("twelve o'clock") comes first, then 才, then the verb 睡觉 ("go to sleep"). No negation is needed — the lateness is built into 才 itself. The same structure works for a friend who didn't arrive until very late or for getting home late at night.
This is a live conversation lesson: you talk out loud with Mei Lin in real time, by voice, not typing. Mei Lin corrects your grammar and pronunciation in the flow of conversation and adapts to your level. The lesson targets this one pattern — 才 (cái) for expressing lateness — and takes roughly 10 minutes. You'll build sentences about going to bed too late, a friend arriving late, and getting home late at night, saying each one out loud until it feels natural.
After this lesson, you can tell someone that things happened later than you wanted. For more practice, visit the HSK 2 lessons hub page.

才 (cái) placed between a time and a verb shows that something happened later than expected. In the sentence 昨晚十二点才睡觉 (zuówǎn shí'èr diǎn cái shuìjiào), it means "I didn't go to sleep until 12 last night" — no separate negation word is needed because the lateness is built into 才 itself.
Each live conversation lesson targets one grammar pattern and takes roughly 10 minutes. In this lesson you focus on 才 (cái) for expressing lateness, building sentences about going to bed late, a friend arriving late, or getting home late at night by talking out loud with Mei Lin.
