Rikkitic: Ya’ll”: This is a colloquial contraction of “you all,” commonly used in Southern American English. It refers to a group of people.
Uh, don't ever spell it that way when you're talking to someone from the southern US, particularly in states that have open carry. It's y'all, and it can also be singular or plural. There's also "all y'all" which encompasses an entire group rather than possibly just a subset.
And pronunciation varies quite a bit, in Texas it sounds more like "y-ow" without any 'l' sound at the end.
