I saw this in an email message.

Problem:
The apostrophe is in the wrong position.

Explanation:
The complete sentence was “I hope to see ya’ll next year.”

A Texan wrote the email message, and I recognized what the writer intended to say.

But “ya’ll” — spelled Y-A-APOSTROPHE-L-L — is not the correct way to write the contraction for the way that Texans say “you all”, the informal plural of the pronoun “you” in some parts of the United States.

An apostrophe in a contraction indicates where letters have been removed.

No letters have been removed between the “a” and the first “l” in the word “all”.

So the apostrophe does not belong after the “a”.

Instead, the apostrophe belongs where the letters “o” and “u” have been removed from the word “you” in the forming of the contraction.

Solution:
“y’all”
