What is the Plural Form of "You"?

The word "you" is supposed to be enough for both singular and plural uses. In order to avoid any misunderstandings of the plural form though, it has been decorated in many ways to distinguish it from the singular. People need to know if you are speaking to them as individuals or if you are speaking to the masses. (This is an issue that does not often come up when we speak to fish, even though the singular and plural forms of that word are identical too.)

The origins of these words are unclear, but some have longer histories than others. Which is the best way? Here are some examples from which to choose:

Youse: This one makes sense because the sound at the end is the same as the one at the ends of "these" and "those", both of which are plural. It fits well into most sentences requiring a plural "you".

Yuz: The quicker form of the previous one, it contains the same sound on the end but doesn't take quite as long to say, leaving more time for the rest of the statement or question.

You guys: This is good for making sure you have the attention of each of the individuals you are addressing. The guys are a group of the men who were all created equal, so let's not get into the gender thing.

Youse guys: A bit redundant, it can be used to remove any doubt that you have each one's attention.

Y'all: This one is actually in the dictionary, making it an official word. It is not the one that would have gotten my vote, but then I'm not registered to vote in the land of Dictionary. In fact, not many are eligible to vote there.

You all: It's pretty self-explanatory. It's the root of "y'all", but it doesn't make sense when addressing two people.

You both: When there aren't enough for the previous one, this can come in handy.

You and you: This can work well for addressing two people, but it might get a little bit cumbersome if you had to repeat it five or more times.

All o'yuz: Another redundant one, it can still be used to clarify that not one single person is excluded.

Both o'yuz: The singular form of this one, of course, is "one o'yuz", but I didn't want to leave it out.

(Each person's name), you: This one can be useful in statements such as, "Larry and Mary, you can ride in Gary's car." It works best for addressing crowds of no more than three, for reasons besides the size of Gary's car.

You: There is always the option of using the grammatically correct version, but if it really worked as well as it should, there wouldn't be so many alternatives.
