How to Say “Again” (in the Future) with 再 (zài)

再 (zài) is “again” for things that haven’t happened yet — Subject + 再 + Verb Phrase: 我下次再来 (“I’ll come again”). It also means “another / some more” (再来一杯咖啡, “another coffee”) and “keep doing / a bit longer” (再想想, “keep thinking”). For “again” in the past, you need 又 instead.

Why this trips learners up

再 (zài) means “again” for the future — something will happen another time. The pattern is Subject + 再 + Verb Phrase: 我下次来 (“I’ll come again next time”), 这部电影我想看一次 (“I want to watch this movie again”). You already say it every day — 再见 is literally “see (you) again.” The key is that it’s planned / not yet done, so it takes no 了.

That’s the big split: 再 = future “again,” 又 = past “again.” 我明天来 (“I’ll come again tomorrow”) vs 他昨天来了 (“he came again yesterday”). If it has already happened, you can’t use 再 — that’s the job of 又…了 on its own page.

再 has two more everyday uses. “Another / some more”: 再 + Verb + a quantity neatly replaces the word “another” — 来一杯咖啡 (“another coffee”), 给我一个 (“give me one more”). And “keep doing / a bit longer”: 再 + a doubled verb, or 再 + Verb + 一会儿 — 想想 (“keep thinking”), 坐一会儿 (“stay a little longer”). (Use the doubled verb or 一会儿, not both.)

One placement rule: 再 sits right before the verb, not before the quantity. It’s 我想喝一杯 (“I’ll have one more drink”), not 我想喝再一杯.

Common mistakes

Avoid: 昨天再下雨了。 zuótiān zài xià yǔ le.
Say this: 昨天又下雨了。 zuótiān yòu xià yǔ le.

Why it happens: 再 is “again” for the FUTURE. For something that already happened again, use 又…了: 昨天又下雨了 (“it rained again yesterday”), not 昨天再下雨了.

Avoid: 我明天再来了。 wǒ míngtiān zài lái le.
Say this: 我明天再来。 wǒ míngtiān zài lái.

Why it happens: Future-again 再 hasn’t happened yet, so it takes no 了: 我明天再来 (“I’ll come again tomorrow”), not 我明天再来了.

Avoid: 我想喝再一杯。 wǒ xiǎng hē zài yì bēi.
Say this: 我想再喝一杯。 wǒ xiǎng zài hē yì bēi.

Why it happens: 再 goes right before the verb, not before the quantity: 我想再喝一杯 (“one more drink”), not 我想喝再一杯.

Compare & contrast

再 — “again” in the FUTURE (not yet, no 了)又 — “again” in the PAST (already happened, +了)The difference
你明天再来nǐ míngtiān zài lái你昨天又来了nǐ zuótiān yòu lái le你明天再来 = “come again tomorrow” (planned — 再, no 了). 你昨天又来了 = “you came again yesterday” (done — 又…了).
我想再试一次wǒ xiǎng zài shì yí cì他又试了一次tā yòu shì le yí cì我想再试一次 = “I want to try again” (future intent). 他又试了一次 = “he tried again” (already happened).
Rule of thumbHasn’t happened yet? Use 再 (no 了): 再来, 再说, 再试一次. Already happened? Use 又…了: 又来了, 又说了. 再 = future “again” (also “another / some more”), 又 = past “again.”

Try it yourself

Say “Try (it) again.” — (Subject +) 再 + verb + count.
