Do I use to or for?

The company was a great success (to, for) Florida.

Either preposition would be correct, but "for" is much better.

Thank you, Ms.Sue.

In this case, the correct preposition to use is "for."

To determine which preposition to use, we need to consider the relationship between the company and Florida. In this sentence, it seems like the company achieved success as a result of its presence in Florida.

To verify this, we can rephrase the sentence by replacing the preposition with the word "because."
The company was a great success because of Florida.

Since "because of" indicates a cause-and-effect relationship, we can conclude that the preposition "for" would be the most appropriate choice.

Therefore, the correct sentence would be:
"The company was a great success for Florida."

Additionally, it's always helpful to consult a reliable grammar source or style guide for more information on correct preposition usage.
