Marks that an action will never happen again

框 · Frame

[subj] 再也不 [verb] (／再也沒 [verb] 過/了)

觸 · Trigger

You want to say something is over for good — it will not happen even one more time.

序 · The move

1Place 再也 before the negator to mark the repetition being cut off.Is the verb one that could otherwise recur?

2Choose 不 for a forward-looking refusal or broken habit; choose 沒 for a past span in which it never happened again.Future/habit → 不; completed non-recurrence → 沒.

3With 沒, close the span with 過 or sentence-final 了.Does the sentence name the stretch the recurrence was absent across?

例 · Examples

1生過having suffered一場大病a serious illness後after，他再也不never again喝酒drink alcohol了(change of state)。

After a serious illness, he never drank again.

界 · Boundary

不再

不再 stops the action from now on, neutral and plain. 再也不 adds 也 to bar even a single recurrence — flat-out, forever.

再…

Bare 再 invites one more time. 再也不/沒 is its negation: that one-more-time is refused outright.

✗ 他再也喝酒了。 → ✓ 他再也不喝酒了。 (再也 needs the negator 不/沒)

✗ 我再也不去過那裡。 → ✓ 我再也沒去過那裡。 (past non-recurrence with 過 takes 沒, not 不)

✗ 她再也不哭。 → ✓ 她再也不哭了。 (forward-looking stop closes with 了)

English "never again" reads as one adverb, so learners drop the Chinese negator; 再也 is only half the frame and must carry 不 or 沒.
