Go back and read what koshergrl wrote you about you/all you-all Fokker.What? English has second-person plural personal pronouns: you, your and yours.Y'all thus fills in the gap created by the absence of a separate second-person plural pronoun in standard modern English.
Yes but those are not specifically plural. They can be either. That's why y'all is needed to specify as plural.
I already corrected that, Chipples.
