I have a sentence where I think I could use either of these two constructions. They seem very similar in meaning, so I'm not sure which I should prefer. There might be some subtle point of grammar hidden in here, or maybe not, I'm not sure.
The two versions are:
- This is sometimes also used to mean such and such.
- This is also sometimes used to mean such and such.
A Google search did not find anything that looks useful.
