I want to know the difference between these two items:
- She couldn't stop herself laughing.
- She couldn't stop herself from laughing.
I assume that No. 2 is wrong, but it seems right!
Both are grammatical. If there’s any difference, it’s that the first might be used to describe someone who is already laughing and couldn’t stop. The second, on the other hand, might be used to describe someone who was unable to refrain from laughing in the first place.
