What does 再 mean?
再 (zài) is the Chinese adverb for 'again' or 'once more' — but specifically for actions that haven't happened yet or are about to happen. 再来一次 ('do it once more / one more time'), 再见 ('see you again' = goodbye). It sits BEFORE the verb. The crucial contrast every learner must master is 再 vs 又 (yòu): 再 looks FORWARD (future repetition or an unfulfilled action), 又 looks BACKWARD (something already happened again). 我明天再来 ('I'll come again tomorrow'); 他昨天又来了 ('he came again yesterday'). 再 also has a sequencing meaning ('then / and then' for ordering future actions): 先吃饭再去 ('eat first, then go'). Don't confuse 再 with 在 (zài, 'at / located at') — same pinyin, completely different jobs.

Don't confuse 再 with
Identical pronunciation, completely different role. 在 = 'at / located at / -ing' (我在家 — 'I'm at home'). 再 = 'again' (再来 — 'come again'). Beginners mix these constantly; remember 再 has 一 on top, like a 'do-over line.'
Both translate as 'again,' but 又 is for past repetition and 再 is for future. The mistake to avoid: 我明天又去 (wrong) — should be 我明天再去 ('I'll go again tomorrow').
