Also sad is the fact that “you” is now used for “thee” and “thou” and such. The older variants could distinguish between “you” plural and “you” singular

You, y'all (small close group), y'all all (larger, further group), and "all y'all" — Southeast Texas (coastal) dialect form that showed up about 25 yrs ago. I suspect it might've been there all along, but only became acceptable at that point?
