N / V-る + に堪えないCannot bear; unbearable; worth doing (in the negative sense)
Has two main uses: 1) Expressing a strong emotion (gratitude, regret) that is so deep it cannot be suppressed. 2) Indicating that something is too terrible to look at or listen to (unbearable).
Common mistakes
- Confusing with ~にたえる, which means 'is worth doing' or 'can handle'
- Confusing with ~に足りない (not worth/sufficient)
- Using in casual conversation; it is strictly for formal speeches or writing
