❌ 食たべる切れない
✅ 食たべ切れない

Using the dictionary form before 切れない is incorrect.

❌ Confusing 切れない with the adjective “not sharp”
✅ 数かぞえ切れない

Context matters: 切れない can mean “not sharp” when used with a blade, so do not mix up the grammar pattern with the adjective.

❌ Using 切れない when the action is impossible for another reason
✅ Using 切れない only when quantity or intensity prevents completion

If the action is impossible because of ability or external rules, choose a different pattern.
