Is there any difference between the meanings of:
1-He smokes when he comes here.
2-He smokes, when he comes here.
Does the comma really change anything?
No difference; the comma is not necessary. If the second is meant to indicate an afterthought, a dash would be better, IMO.Originally Posted by navi tasan
He smokes -- when he comes here.
That might imply that he doesn't smoke other places.
