The Forward-Looking Projector: Queuing an action to repeat in the future.
再 repeats an action ahead in the future (play it again), while 又 repeats what already happened in the past.

HSK-G-18Common Usage & Traps
Why does Chinese use 再 for future repetition but 又 for past repetition?
再 points forward to repetition that has not happened yet; 又 points backward to repetition that already happened.
English again covers both past and future repetition with one word. Chinese splits this into 再 for future or hypothetical repetition and 又 for past repetition. Learners who translate again as 再 everywhere produce wrong sentences about the past. The fix is to check whether the repeated action already happened before choosing the helper word.
| Situation / Pattern | Formula | Natural | Avoid |
|---|---|---|---|
| Future repetition | Subject + 再 + Verb | 我明天再来。 | 我明天又来。 |
| Past repetition | Subject + 又 + Verb + 了 | 他昨天又来了。 | 他昨天再来了。 |
| Polite goodbye | Fixed expression 再见 | 再见！ | 又见！ |
Where does 再 go in a Chinese sentence?
再 always sits before the verb, never after it.
English again often lands at the end of a sentence, so learners copy that habit into Chinese. Chinese adverbs like 再 must appear before the verb they modify. Putting 再 after the verb sounds broken and is a very common beginner mistake. Remember the slot: subject, time, 再, verb.
| Situation / Pattern | Formula | Natural | Avoid |
|---|---|---|---|
| Simple future repeat | Subject + 再 + Verb | 我再试一次。 | 我试再一次。 |
| With time word | Subject + Time + 再 + Verb | 我明天再去。 | 我明天去再。 |
| With location | Subject + 再 + 去 + Place | 他再去学校。 | 他去学校再。 |
