"ya'll" well this is as southern as it comes, generally singular, but has the unique characteristic of being plural, and at the same time.



ya'll is not singular. It is always plural although sometimes misunderstood. It is a contraction for you all. When directed at an individual it is still plural and is in reference to some group to which the individual belongs. It is rather funny when the term is used incorrectly in a movie or TV show because the writer was not from the south. I recall a line in a movie when someone said to an individual, " I saw y'all near the store." This would only be said if the speaker was talking about the group that the other person was among. It would not be a reference to an individual.

Maybe this is subject matter for a more advance y'allbonics course.
