So I was talking to my fiancee and she said "more sharp" to which I said "you mean sharper?". This is in context of talking about her current earrings being "more sharp" then her usual ones. She then insisted that "more sharp" is a proper phrase. I disagree.
So we come to you, oh interwebs, to determine whom is correct.
Is "more sharp" a proper phrase, especially in this context, or is it an improper phrase?
