I've seen it spelled both ways. Are both correct?
It should be the first: "Y'all"
In contractions, apostrophes represent where letters were taken out. "Y'all" is a contraction of "you all". the "ou " was taken out, so you put an apostrophe were it used to be, giving you "y'all".
6Let me make this additional point, because, as a Texan, this drive me nuts when I see it on TV: "y'all" is second person, PLURAL, not SINGULAR. "Y'all" is more than one person. Up north, it's "you guys". Jan 28, 2011 at 20:34
And in Australia, it's "youse"– chimpJan 28, 2011 at 21:45
2Except in Pittsburgh, where it's "y'uns". Jan 28, 2011 at 21:51
3Just "you" can also be plural though. Jan 28, 2011 at 22:37
2Just so, @phoog. Here in North Carolina, I have heard waitresses use "y'all" in addressing a singular you, while addressing the group of the table with the redundant "all of y'all," as in "All of y'all want water?"– rajah9Nov 18, 2013 at 14:04
Y'all is a contraction of "you all", so I would assume that y'all is the correct spelling.
Wikipedia gives some background on the topic.
what other contraction cuts out letters from the first word? I can't think of any. i agree its a tongue in cheek argument, pretending that the question is important (even when you're from Texas [notice the contraction for you're]). but it boggles my mind to see Northerners assume the contraction is for "you all." Southerns wouldn't have abbrev that phrase in such a way. however, when saying "ya all," them words tenda run tagedder. When you say "you will" the distinction of the "wi" sound tends to disappear, so its dropped when spelling "you'll." Similarly, "ya all" became "ya'll."

1Other contractions that cut out sounds (letters are not cut out in contractions—it’s the sounds that matter) include ’tis (etc.), ’cause, the Aussie greeting g’day, and so on. I don’t see how that’s relevant, though. Whether y’all is from ya all, you all, or ye all, it is clearly the first vowel that’s being dropped, not the second. Jan 27, 2014 at 11:23
As a Northerner, I have seen "ya" as an acceptable colloquialism for "you". However, I've never heard/seen "ya" go with "will", it has always been shortened to "you'll". The "ya" is well established in the Midwest due to the accents inherited by the northern European immigrants. The same goes for the urban population which has retained many southern speech tendencies. That may be due to the more often used conjugations/variants of "to be going to" other than "will" in order to express the future. Although, one might hear something like "ya'll" as a condensed way of saying "yeah, I will"
I would say it is a moot point, since the kind of people who believe that 'correct' is a meaningful word in this sort of question will generally not accept the word, however spelt.
9That's a narrow view. If you are writing a fictional story, say, and have a character who uses phrases like "Y'all," it is important to know the "correct" way to spell it, no? Nov 29, 2010 at 4:01
ya'llas their preferred spelling, but it makes no sense when you break down the contraction.
