- There used to be a library over there.
- There was a library over there.
What’s the difference in meaning between the above two sentences?
Both have the same meaning, but I think #1 with “used to” emphasizes the fact that the library is no longer there.
Just an additional point - ‘used to’ often indicates a sense of regret that something is no longer there whereas ‘was’ simply states the fact that something has gone.
Yes, ‘used to’ could reflect sort of personal experience!
