I believe the Georgian version is different. “Y’all” is singular while “all y’all” is plural.

From North Carolina originally. "Y'all" is singular, "all y'all" is plural, and "all y'all MF'ers" is when you are angry and it could be singular or plural depending on the connotation.

You must have moved before you started speaking. But nice to see people in the thread recognizing it's not just Texas

Y'all is plural. All y'all is short for all of y'all.

Georgian here. No. "Y'all" has never been singular.
