再也 + 不 / 没 + … 了 (לעולם שוב)

Two friends have not met since graduation

• graduation毕业bì yèback后hòuwe / us我们wǒ menever again再也zài yěnot / haven't没méito appear见jiànexperience marker过guoflour面miàn。 — “After graduation, we have not met again.” This reports the absence of another meeting during the stated period.
• Compare I我wǒever again再也zài yěnot不bùgo去qù那家店nà jiā diàn(completed / change)了le。 — “I will never go to that shop again.” That is a strong decision about future visits, not the same kind of past report.

Express a strong intention with not不bù

• ever again再也zài yě + not不bù + verb phrase + (completed / change)了le can express “never again”: I我wǒever again再也zài yěnot不bùgo去qù(completed / change)了le / I我wǒever again再也zài yěnot不bùto buy买mǎithis这个zhè ge(completed / change)了le。
• The wording presents a firm stance. It does not make it logically impossible for a person to change their mind later.

I我wǒever again再也zài yěnot不bùgo去qù了le。

Report no repetition with not / haven't没méi

• ever again再也zài yě + not / haven't没méi + verb phrase can report that something did not happen again: graduation毕业bì yèback后hòuwe / us我们wǒ menever again再也zài yěnot / haven't没méito appear见jiànexperience marker过guoflour面miàn。
• This example has experience marker过guo and no final (completed / change)了le. Do not require every ever again再也zài yě sentence to end in (completed / change)了le or turn a report so far into proof about every future day.

Compare absence, refusal and inability

• ever again再也zài yěnot / haven't没méito appear见jiànexperience marker过guoflour面miàn reports no further meeting. ever again再也zài yěnot不bùgo去qù那家店nà jiā diàn(completed / change)了le presents an intention not to visit. ever again再也zài yěto try to find找zhǎonot to arrive不到bú dào那本书nà běn shū(completed / change)了le reports inability to find the book now.
• All concern no recurrence or continuation in context, but their time and reason differ. Read the negative predicate and the stated boundary.

State the relevant time boundary

• “After graduation” supplies a starting point for the no-meeting account. It does not by itself state that meeting again is impossible.
• For an outcome question, distinguish what is reported from what is predicted. A sentence about past absence needs additional evidence before a permanent-future claim.

Translate the whole negative pattern

• To state a firm decision, use a suitable not不bù pattern. To report no further experience, use a suitable not / haven't没méi pattern with the context.
• Keep ever again再也zài yě with its negative expression in the patterns taught here. Explain the actual meaning rather than treating all examples as an angry refusal.
