In addition to where (as in Which way you going?), which way occasionally also appears to be used to express 'how', in which case we would be dealing with three compound expressions. Consider the following example from my sociolinguistic interviews: I don't care what color you is. We are one anyway. Any which way you put it! Even you little white - you little brighter than me, but we're still one! However, according to one of my Bahamian consultants, how is the default expression in this case.
