All you all?

I’m southern, let me help. “Y’all” refers to a group of people. It usually means the group of people that the speaker is speaking to, but you can also define the group, like “y’all in the other room” or “y’all Canadians”.

“All y’all” refers to the entirety of that group, as opposed to a subset of a group, which would be “summa y’all”, or none of a group, which would be “nunna y’all”.

I think people would’ve felt it more natural if I wrote “all of y’all” instead, but I thought the “of” was unnecessary.

But you wrote the slang correctly! Unfamiliarity with the slang is an opportunity to educate about our language.

(Source; we been sayin' all y'all since before y'all non-Southerners were even sayin' y'all.)

It’s not a language as much as a mouth full of chew and a belly full of moonshine.
