all y'all

Etymology
From +  (itself from  + ).

Usage notes

 * All y'all is used in the Southern United States when a speaker wishes to include everyone being addressed. Y'all may refer to an indefinite set of members of a group, but all y'all definitively includes everyone in the group.
 * Like (see that entry's usage notes) and most other second-person plural pronouns, all y'all (and y'all all, which mirrors e.g. they all) can be said to one individual with an implied plural "and your group".
 * This form of y'all can be considered incorrect in certain parts of the American South as being redundant.
 * While "All y'all" is acceptable as either the subject or object in the structure of a sentence, the variant, "y'all all," should be used principally as the subject.

Alternative forms

 * all o' y'all
 * all of y'all
