@Crazychick I am from the Britain, their are many accents that alter the Queens English although a lot of the older more thicker (Stronger) accents are dying out
@SharonP I am from Britain too. Manchester in fact. Accents are one thing, but replacing one word with an unrelated word that isn't even pronounced the same is just weird.
@Crazychick well I am not getting into a war with you but, Look around and you will find a lot of people will replace "of" and "Have" on occasions, but I am not so picky as to point it out
@Crazychick I think using "of" in place of "have" might be rather more common around London. Some of the same people might also say "arks" instead of "ask". These aren't exactly wrong but perhaps a form of language evolution.
