Between x to y

[marketmaster]

More than one announcer at a local, university-affiliated has started using the phrase "between x to y." This grates on my ear. I have always used "between x and y." Is the former grammatically correct?

[Bennevis]

It might depend on context. Here is a line from the UCLA Visualization Portal:

By saying there is a knot here, we're suggesting that the relationship between x to y for x < 10 is different from the relationship for x > 10.

[Bennevis]

"to" is probably used when talking about trajectories/trace-routes.

"The relation between x to y ..." is incorrect in standard English.
I can't think of a good context for "between x to y", unless x can stand for two things.

I agree.

I can't think of a good context for "between x to y", unless x can stand for two things.

I can't think of an example for that. Can you?

Where x means two things? Yes.
I now live [in a small town] between Brisbane and Noosa. I'm moving to Sydney.
I'm moving from between Brisbane and Noosa to Sydney.
x = "Brisbane and Noosa"

"Move the painting from between these two windows to the other wall."

If x and y have numerical values, it might not refer to any kind of extent. 'Let the water boil for between 1 to 2 minutes.' (The 'between' is redundant there, but it still might be said)..

This seems to be the only case in which it's used fairly commonly by native speakers. At least according to COCA.

[BobK]

Phew! ('Things go better with COCA' as they say.)

Thanks to all. I should have given the actual example which has been in forecasting future temperatures, i.e. "tomorrow's temperature will be between 75 to 80 degrees."
