The one thing that English lacks, well, one of the many things, is a second person plural seperate from the second person singular. At least, this is the cae in most places. The south, despite how much of the country holds it in contempt, has resolved this pressing linguistic deficiency.
Yes, that wonderful contraction. I'd be so apt as to write it without the apostrophe, yall. I mean, tomorrow used to have a hyphen between to and morrow, but we got rid of that superfluous grammatical mark.
So the next time you need to use the second person plural pronoun, just use "Yall."
