Are all these sentences correct and is there any difference between there meanings:

[color=red]1-He rarely goes there.
[color=indigo]2-He goes there rarely.

[color=red]3-He seldom goes there.
[color=indigo]4-He goes there seldom.


Not a tutor.

They all make sense. The word order of the second version each time is less common, but it is correct.

By the way Ebenezer, once again I had to remove a duplicate message from you.
