N3 · 03 Conditions and consequences
Says that something stays the same until a condition is met.
Verb ない-form + 限り. The result continues as long as the condition does not happen. It sounds firm and goes with negative or hard-to-change results. Compare 〜ないと, which is just "if not".
Examples
練習しない限り、上手にはならない。
Unless you practice, you will not get good.
本人が謝らない限り、私は許さない。
As long as the person himself does not apologize, I will not forgive him.
