就 (jiù) vs 才 (cái) in Chinese
就/才
就 and 才 both comment on timing, in opposite directions. 就 says something happened early, soon, or easily (他八点就来了 — he came as early as 8). 才 says it happened late, or only after effort or conditions (他九点才来 — he didn't come until 9). Same clock, opposite feeling.

MODEL
就 early or soon, 才 late or only then
Read the structure
就 and 才 both comment on timing, in opposite directions. 就 says something happened early, soon, or easily (他八点就来了 — he came as early as 8). 才 says it happened late, or only after effort or conditions (他九点才来 — he didn't come until 9). Same clock, opposite feeling. Keep the model 就 early or soon, 才 late or only then visible while you compare each sentence.
我马上就来。
I'll come right away.
Choose the right context
就 for "as early as / right away": 我马上就来。 才 for "not until / only then": 他昨天才知道。 才 after a condition — "only then": 说了三遍他才懂。
他八点就到了。
He arrived as early as 8.
Respect the boundary
Treating 才 + 了 as always wrong — 了 can appear with quantities, duration, or a new situation; learn the meaning of the whole sentence。 就 for "not until" (late) — that reverses the meaning; use 才: 九点才来。 Putting them after the verb — both are adverbs and sit before it.
他九点就才来。
(He didn't come until 9.)
Repair the pattern
就 and 才 stacked for one timing meaning: 就 and 才 express opposite viewpoints and cannot be stacked here. To say "not until 9", choose 才: 他九点才来。 才 placed after the time and verb: 才 is an adverb and belongs before the verb, while the time phrase comes earlier. Put the sequence in the order time + 才 + verb: 他九点才来。
他九点才来。
Use the repaired structure without changing the intended meaning.

05 / REPAIR
Compare Right and Wrong
Compare the smallest meaningful change. Each explanation identifies a placement, scope, form, or clause relationship instead of treating the whole sentence as one undifferentiated mistake.
他九点就才来。
他九点才来。
就 and 才 stacked for one timing meaning
就 and 才 express opposite viewpoints and cannot be stacked here. To say "not until 9", choose 才: 他九点才来。
他来九点才。
他九点才来。
才 placed after the time and verb
才 is an adverb and belongs before the verb, while the time phrase comes earlier. Put the sequence in the order time + 才 + verb: 他九点才来。
他九点就才来。
Choose 才 for 'not until'; do not stack 就 and 才: 他九点才来。
他来九点才。
Put the time before 才 and the verb: 他九点才来。
我马上才就来。
For 'right away', use 就 before the verb without 才: 我马上就来。

Apply It in Your Sentence
Write one original sentence with 就/才. Your draft moves to the checker through this browser session, selects this grammar point as the first review focus, and waits for you to submit.
08 / QUESTIONS
就 (jiù) vs 才 (cái) Questions
What is the difference between 就 and 才?
就 = early / soon / easily (八点就来 — came as early as 8). 才 = late / only then / after effort (九点才来 — didn't come until 9). Same time, opposite attitude.
Can 才 be used with 了?
Sometimes. 他九点才来 is the basic "not until 9" pattern, but 了 can appear when the sentence adds a quantity, duration, or new situation, such as 他才来了两天. Do not judge 才 + 了 without context.
How do I say "right away / as soon as"?
就: 我马上就来 (I'll come right away), 说完就走 (leave right after finishing). For "not until", switch to 才.
