When do I use 还 vs 再 for expressing 'more'?

Use 还 when you want to say 'still want more' as a continuation of desire (还要). Use 再 when you want to perform an action one more time in the future (再吃). For objects, 还来一个 means 'still coming one' (maybe in a list), while 再来一个 means 'bring another one' (future).

Can 还 ever mean 'again'?

In some fixed expressions or with certain verbs, 还 can imply a repeated action, but usually it doesn't mean 'again' in the same way as 再. For example, 他还来 can mean 'he still comes' (ongoing) or 'he also comes' (additional), but not 'he comes again' (for which you'd use 再来).

How do I use 还 and 再 in negative sentences?

For 还, the negative is 还没 (hái méi) meaning 'not yet' for verbs of change, or 还不 (hái bù) for 'still not' for stative verbs. For 再, the negative is usually 不再 (bù zài) meaning 'no longer' or 'not again', e.g., 我不再去了 'I won't go again'.

还 vs 再 (hái vs zài): still vs again

还 (hái) indicates that a state or action continues to the present, often meaning 'still' or 'yet'. 再 (zài) indicates a future repetition or continuation of an action, meaning 'again' or 'another (time)'. The key distinction is time reference: 还 looks backward at ongoing situations, while 再 looks forward to a repeated event.

还 and 再 are both adverbs that relate to continuation or repetition, but they operate in different time frames and contexts. 还 is used for an ongoing state or action that persists up to the present (still, yet), and can also mean 'also' or 'additional' (e.g., 还有). 再 is used for an action that will be repeated or continued in the future, often in commands, plans, or invitations (again, another time). A common trick: if you can replace the word with 'still' in English, use 还; if you want 'again' referring to a future event, use 再.

When to use each

还hái

still, yet, also

Use 还 when something is continuing from before into the present, such as 'still doing something' or 'not yet finished'. It is also used to mean 'also' or 'in addition' (e.g., 还要 'still want' ≈ 'also want'). In negative sentences (还 + 没/不), it conveys that an expected change has not occurred yet, like 'still not'.

还 can also appear in comparative constructions meaning 'even' (e.g., 比…还…), but that is a separate usage from the 'still/also' sense.

再zài

again, another time, more

Use 再 when an action happens another time in the future, or when you want to add more of an action (e.g., 再吃一点 'eat a bit more'). It is common in polite requests (请再…) and future plans (明天再去). It implies that the action has not occurred yet—it is a repetition yet to come.

再 cannot be used for past repetitions; for that, use 又 (yòu). It also appears in phrases like 再见 (zàijiàn, 'goodbye', literally 'see again').

Common mistakes

Using 再 for 'still' in ongoing actions: ✗ 我再看书 (meaning 'I read again' not 'I am still reading') → use 还: 我还在看书。
Using 还 in commands for 'again': ✗ 请还说一遍 → use 再: 请再说一遍。
Using 再 for past repetition: ✗ 昨天我再看了那部电影 → use 又: 昨天我又看了那部电影。
Confusing 还 and 再 when both mean 'more': 还要 = 'still want' (continuing desire), 再要 = 'want another' (future addition). In many contexts they are interchangeable but with a nuance difference: 还 more about continuation, 再 about repetition.
