I've been wondering, if anyone knows for sure:
I know saying "I've" is fine for contraction I and the modal form of have.
But, it seems to be an error to use the contraction with the non-modal form of the verb as in:
"I've an answer to your question."
I don't think that is correct, American English. I believe it works for Brittish English.
It would be the same as contracting I and will:
Correct: I think I'll have another.
Incorrect: I'll my beliefs into reality.
Agreed? Any thoughts?
