The pronoun you (stressed //, unstressed //) is the second-person personal pronoun, both singular and plural, and both nominative and oblique case, in Modern English. The oblique (objective) form you functioned previously in the roles of both accusative and dative, as well as all instances after a preposition. The possessive forms of you are your (used before a noun) and yours (used in place of a noun). The reflexive forms are yourself (singular) and yourselves (plural).

In standard English, you is both singular and plural; it always takes a verb form that originally marked the word as plural, (i.e. you are, in common with we are and they are). This was not always so. Early Modern English distinguished between the plural ye and the singular thou. As in many other European languages, English at the time had a T-V distinction, which made the plural forms more respectful and deferential; they were used to address strangers and social superiors. This distinction ultimately led to familiar thou becoming obsolete in modern English, although it persists in some rural English dialects. Because thou is now seen primarily in literary sources such as the King James Bible (often directed to God, who is traditionally addressed in the familiar) or Shakespeare (often in dramatic dialogues, e.g. "Wherefore art thou Romeo?"), it is now widely perceived as more formal, rather than familiar.
Informal plural forms
Despite you being both singular and plural, some dialects retain the distinction between a singular and plural you with different words. Examples of such pronouns sometimes seen and heard are:
- y'all, or you all – southern United States and African American Vernacular English. Y'all however, is also occasionally used for the second person singular.
- you guys – U.S., particularly in the Midwest, Northeast, South Florida and West Coast; Canada, Australia. Used regardless of the genders of those referred to
- you lot – UK
- yous(e) – Ireland, Tyneside, Merseyside, Central Scotland, Australia 
- yous(e) guys – in the U.S., particularly in New York City region, Philadelphia, Northeastern Pennsylvania, and the Upper Peninsula of Michigan;
- you-uns/yinz – Western Pennsylvania, The Ozarks, The Appalachians
- ye/yee/yees/yiz – Ireland, Tyneside
- allyuh – Trinidad & Tobago
Although these plurals are used in daily speech, they are sometimes not considered acceptable in formal writing situations.
Third person usage
You is usually a second person pronoun. In formal English, the indefinite pronoun one can be used in the third person to refer to an indeterminate person. However, in informal usage, English speakers usually replace one with you.
- Example: "One cannot learn English in a day" becomes "You cannot learn English in a day".
You is derived from Old English ge or ȝe (both pronounced roughly like Modern English yea), which was the old nominative case form of the pronoun, and eow, which was the old accusative case form of the pronoun. In Middle English the nominative case became ye, and the oblique case (formed by the merger of the accusative case and the former dative case) was you. In early Modern English either the nominative or the accusative form had been generalized in most dialects. Most generalized you; some dialects in the north of England and Scotland generalized ye, or use ye as a clipped or clitic form of the pronoun.
The specific form of this pronoun can be derived from PIE *yū(H)s (2nd plural nominative). It is most widespread in the Germanic languages, but has cognates in other branches of Indo-European languages such as Ved. yūyám, Av. yūš, Gk. humeis, Toch. yas/yes, Arm. dzez/dzez/cez, OPruss. ioūs, Lith. jūs, Ltv. jūs, Alb. juve, ju. In other Indo-European languages the form derived from *wō̆s (second person plural oblique) began to prevail: Lat. vōs, Pol. wy, Russ. вы [vy].
In the early days of the printing press, the letter y was used in place of the thorn (þ), so many modern instances of "ye" (such as in "Ye Olde Shoppe") are in fact examples of "the" (definite article) and not of "you". This use of letters in printing may have indirectly helped to contribute to the displacement of thou by you, and the use of you in the nominative case.
