We use “you” to refer to people in general or to any person in a hypothetical situation. “If you don´t want to fail, “you” must persevere”. YES. IT IS AN IMPERSONAL ‘YOU’.

One, you, we and they are generic personal pronouns. We can use one, you, we and they to refer to ‘people in general’.

‘You” was originally plural, “thou” was the singular. There was a shift to using the plural as the polite form, eg. monarchs say ‘we’ for I, so gradually the ‘you’ plural began to be used by everybody.

Though “y’all” is inherently plural, in the instance of addressing a larger group of people, “all y’all” is more of a casual, slang phrase that’s sometimes used. The only right way to spell the contraction of “you” and “all” is “y’all.” “Ya’ll” is incorrect and a misspelling of the word, so don’t use it.

While “y’all” is actually a contraction for “you all” and is therefore technically correct, it is most commonly used in place of the plural form of “you.” The apostrophe after the “y” represents the lost “ooo” sound from the letters O and U. In Spanish, the second-personal plural pronoun is ustedes or vosotros.
