Genuine question here; does AAVE have an accepted grammar? I don't mean necessarily a written canon, but anything that's not "make it up as you go" ad-hoc style. (And yes, I realize all language has some evolutionary context to it.) Without rules, there's no way to break them, and thus no meaning for "mistake".
