I am sorry if anyone has taken offence at my comments about Hull, but I do live in the locality, so have an implied permission to be critical. I am also yorkshire born and bred, but I don't talk "lark thaat". I understand about dialect too, and dialect as far as I was aware is about pronunciation, not about gramatical sentence structure. eg "have you seen t'whippet" and "I've booked it on t'internet". Both are common uses of the use of t' instead of the, and not changing a whole word for an incorrect one such as "I were" instead of "I was" or "we was" instead of "we were". I hope that makes some sense?
