I looked at “Between A and B vs from A to B”, but it didn’t mention a third variation I’ve been hearing more often, recently.
Even on the Australian national broadcaster, the ABC, I’ve heard statements by reporters like
The cost was estimated to be between A to B dollars.
Have the rules of grammar changed, or is this as ungrammatical as I think it is?
It is not right to use between A to B, or from A and B for that matter, though the former is a common error.
Intuitively, to suggests motion just like from, while between is a reference to two objects and should be paired with and.
