Y'all - Wikipedia
https://en.wikipedia.org/wiki/Y'allY'all is a contraction of you and all, sometimes combined as you-all. Y'all is the main second-person plural pronoun in Southern American English, with which it is most frequently associated, though it also appears in some other English varieties, including African-American English and South African Indian English. It is usually used as a plural second-person pronoun, but whether it is exclusively plural is a perennial subject of discussion.
