How correct it is saying: “I don’t ever go to work by bus” instead of “I never go to work by bus” Does the meaning of these two questions change?
Both these sentences essentially mean the same thing. If I had to choose, I think the second one is more idiomatic, and probably what I would say.
The first one is ok, but a little open-ended in my opinion. You could potentially follow it up with an exception: I don’t ever go to work by bus, but I may try it this week.
The sentence with never is more final to me.
