Y’all = singular
All’s Y’all = plural
From that website:
“while “y’all” may refer to an indeterminate number of people, “all y’all” refers to everyone who is being addressed”.
My grandmother (Virginia) always got mad when she heard ‘Y’all’ used to refer to just one person. She thought the use mocked people from the South, who properly used it to refer to more than one.
All’s Y’all = plural
Not quite. It depends on where you're from. Y'all refers to multiple people, but only up to a certain number. Depending on the locale, one prefixes "All" to "Y'all" if there are more than 3 to 5 people being addressed.
"All y'all kids better git yer bikes out the driveway. They's a-fixen to git runned over."
I forgot all about that one.
“Y’all = singular”
You must not be from the South. “Y’all” is never ever singular. It is always plural. If I were to ask you, and you were alone, “When are y’all coming for a visit” that means you along with your family.
The “all” in “all y”all” (and you don’t have that right, it is never all’s y’all) is merely an intensifier.
Yall doesnt need an apostrophe.
I got heavy roots in Kentucky. Any you’ins played in red dirt? Boy, I’ll tell ya.
Actually it's not. You walk into a shop alone and the attendant asks, how y'all doin'?
In the deep south where everyone used to know everyone and their families it was about being polite. How y'all doing is a question about the family not about you personally. Only a Yankee would think it was all about her.
