I tease non-Texans that Texan English is actually superior to normal American English because it supports second-person plural via "Y'all" exactly as mentioned in this article... "you guys" is, to some ears, sexist, and "youse guys" (a New York-ism) is a little too old-school Italian. English lost its second person plural when we switched from Thou (second person singular formal + Thee=second person singular informal…
This whole thread is extremely confusing to this Appalachian native. Y'all is used quite widely throughout the entire southeast. It's recognized, if not used, through the entire country. I've also seen its use increasing in the Midwest as it seeps out of the south. Do many people actually see this as a novel word? It's incredibly common from my perspective here in Ohio.
Where I live, yeah. I live in Minnesota and I intentionally use "y'all" here because I think it neatly fills the need and I want it to catch on, but it definitely feels like an affectation. It's not something you hear unless someone is from out of town or going out of their way to use it intentionally (like me).
