Mood Adverbs: 才, 都, 就, 正好
语气副词：才、都、就、正好
Express the speaker's attitude about timing and appropriateness using mood adverbs
Place the mood adverb before the verb to convey your emotional attitude about the timing or appropriateness of the action. These adverbs change the "feel" of a sentence without changing the facts.
才 implies "not until / only then" (later than expected). 都 implies "already" (with impatience). 就 implies "as early as" (sooner than expected). 正好 implies "just right / coincidentally."

Understanding 语气副词：才、都、就、正好
Mood adverbs are the secret sauce of natural Chinese. They do not change what happened — they change how you FEEL about it. Consider the same fact: "He arrived at ten." Now add attitude. 他十点才到 means "He did not arrive until ten" — you are annoyed he was late. 都十点了他才到 intensifies it — "It was already ten and he STILL just arrived." 他十点就到了 means "He arrived as early as ten" — you are impressed he came so soon. 正好十点到 means "He arrived at exactly ten" — perfect timing. Same fact, four completely different emotional messages. This is what makes Chinese so expressive.
Key Points
- 才 (cái) = not until / only then — implies the action was later or less than expected.
- 都 (dōu) = already — expresses impatience or emphasis that time has passed: 都三点了 (It is already three!).
- 就 (jiù) = as early as / right away — implies the action was sooner or more than expected.
- 正好 (zhènghǎo) = just right / exactly / coincidentally — perfect timing or fit.
- 才 vs. 就: same event, opposite feelings. 才 = too slow, 就 = impressively fast.
- 都……了 is a common pattern for expressing "it is already…": 都十二点了！(It is already midnight!)
- 才 sentences usually do NOT end with 了: 他九点才来 (not 他九点才来了).
- 正好 can mean "coincidentally": 我正好也想去 (I happen to want to go too).
The 才 vs. 就 contrast reveals Chinese speakers' expectations. When parents say 你才考了八十分 (You only scored 80), the 才 shows disappointment. When they say 你就考了一百分 (You got a perfect 100!), the 就 shows pleasant surprise. Understanding these emotional cues is key to reading between the lines.
Key Vocabulary
Example Sentences

Coincidental convenience
Common Mistakes
才 sentences generally do not end with 了. The 才 itself implies the action was delayed — adding 了 is redundant and unnatural.
If seven o'clock is impressively EARLY, use 就 (sooner than expected). 才 would imply seven was LATE.
正好 typically needs 了 to indicate the coincidence has occurred. Without 了, the sentence feels incomplete.
The 都……了 pattern requires 了 to express "it is ALREADY three" — the 了 conveys the change or accumulated time.
Practice Exercises
Tips & Tricks
The 才 vs. 就 contrast is one of the most important grammar points in all of Chinese — practice it daily.
When expressing impatience about time, use 都……了: 都八点了！都星期五了！都三月了！
正好 is a wonderful conversation word — use it when something works out well: 正好我也饿了 (I happen to be hungry too).
Remember: 才 = dissatisfied (too late/too little), 就 = impressed (so early/so much). Same facts, opposite feelings.
Test yourself: take any timed event and say it with both 才 and 就 to feel the emotional difference.
Homework
Pick five events from your week and describe each one twice: once with 才 (expressing that it was late or slow) and once with 就 (expressing that it was early or fast). Then add three sentences using 都……了 for impatience and three using 正好 for coincidences.
