You prototypically refers to the addressee along with zero or more other persons, excluding the speaker. You is also used to refer to personified things (e.g., why won't you start? addressed to a car).[25] You is always definite even when it is not specific.
Semantically, you is both singular and plural, though syntactically it is almost always plural: i.e. always takes a verb form that originally marked the word as plural, (i.e. you are, in common with we are and they are).
