*******************************************************************

Except in Alabama.

“Y’all” is plural - conjunction of “You all”.

“Are y’all coming to dinner?”

But also heard might be: “Are y’all ALL coming to dinner?” (Meaning - “I better get more food!”

To us in our part of Alabama, the singular would be “you”.
