One can contract I have to I've when have is a helping verb, e.g.
I've got an octopus in my pants.
Is contracting the main verb technically incorrect or merely antiquated? My father loves to say,
I've a month-old smoked shoulder I can cook for dinner,
and he sounds like a crazy old man when he does. I would like to know if I can shut him down by informing him that he is incorrect. :)
