If you’ve ever taken the New York Times’ Dialect Quiz, you know that Southerners — and Soda Citizens — have their own special lingo.

The quiz asks questions that pinpoint Southeastern dialect, like “How would you address a group of two or more people?” If you answered “y’all,” your Southern side is showing. This versatile word is a part of almost every Southerner’s vocabulary, but how did the word come to be + how the heck do you spell it?

While the word “y’all” is ubiquitous among native Southerners, plenty of people will tell you it’s not a word at all. (Sorry, but y’all are wrong.)

Unlike many languages, English lacks a second-person plural, so the word “you” can be used to address a single person or a group of people. For clarity, many American English speakers have adopted the phrase “you all” to indicate a multitude + “y’all” just so happens to be a grammatically acceptable contraction of that (although similar words like “you’uns” or “youse” are typically less adored by strict grammarians).

But there are rules, y’all. As with any linguistic contraction — think: “I’m,” “she’s,” “won’t,” “we’ve” — the apostrophe replaces letters that are missing from the full word or phrase. Since “y’all” is the abbreviated form of “you all,” the apostrophe is placed where the o + u are missing. Thus, “y’all,” not “ya’ll.”

Another benefit of using it? It’s the most inclusive term you can use to address folks because it encompasses everyone.
