I'm married to a Mississippian, I've heard "y'all" applied to groups, individuals and pets. "Fixin"
is another one of them great words. Although I'm a card carrying "Yankee Jewboy", I'm working on an English to Southern dictionary but it's a long row to hoe.
I'm hoping all y'all wlll understand what I'm fixin' to do. Bah-bah, now.
