HSK 5 grammar · adverb
再也不/没
再也不/没 — never again
Pattern
+
about the future

about the past
( ) can be left out · other words may come before, between and after
How it works
再也不 / 再也没 add 再也 before a negation to stress "never again / not any more." 再也不 refers to the future ("won't ever again"); 再也没 to the past ("never … again," often with 过).
Examples

Wǒ zài yě bù xiāngxìn tā de huà le.
I'll never believe what he says again.
从那以后,我再也没见过他。
Cóng nà yǐhòu, wǒ zài yě méi jiànguo tā.
After that, I never saw him again.
