Plural forms from other varieties

Although there is some dialectal retention of the original plural ye and the original singular thou, most English-speaking groups have lost the original forms. Because of the loss of the original singular-plural distinction, many English dialects belonging to this group have innovated new plural forms of the second person pronoun. Examples of such pronouns sometimes seen and heard include:

• y'all, or you all – southern United States,^[7] African-American Vernacular English, the Abaco Islands,^[8] St. Helena^[8] and Tristan da Cunha.^[8] Y'all however, is also occasionally used for the second-person singular in the North American varieties.
• you guys [ju gajz~juɣajz] – United States,^[9] particularly in the Midwest, Northeast, South Florida and West Coast; Canada, Australia. Gendered usage varies; for mixed groups, "you guys" is nearly always used. For groups consisting of only women, forms like "you girls" or "you gals" might appear instead, though "you guys" is sometimes used for a group of only women as well.
• you lot – United Kingdom,^[10] Palmerston Island,^[11] Australia
• you mob – Australia^[12]
• you-all, all-you – Caribbean English,^[13] Saba^[11]
• a(ll)-yo-dis – Guyana^[13]
• allyuh – Trinidad and Tobago^[14]
• among(st)-you – Carriacou, Grenada, Guyana,^[13] Utila^[11]
• wunna – Barbados^[13]
• yinna – Bahamas^[13]
• unu/oona – Jamaica, Belize, Cayman Islands, Barbados,^[13] San Salvador Island^[8]
• yous(e) – Ireland,^[15] Tyneside,^[16] Merseyside,^[17] Central Scotland,^[18] Australia,^[19] Falkland Islands,^[8] New Zealand,^[11] Philadelphia,^[20] parts of the Midwestern US,^[21] Cape Breton and rural Canada^{[citation needed]}
• yous(e) guys – in the United States, particularly in New York City region, Philadelphia, Northeastern Pennsylvania, and the Upper Peninsula of Michigan;^{[citation needed]}
• you-uns, or yinz – Western Pennsylvania, the Ozarks, the Appalachians^[22]
• ye, yee, yees, yiz – Ireland,^[23] Tyneside,^[24] Newfoundland and Labrador^[11]

First person usage

The practice of referring to oneself as you, occasionally known as tuism,^[26][27] is common when talking to oneself.^[28][29] It is less common in conversations with others, as it could easily result in confusion. Since English lacks a distinct first person singular imperative mood, you and let's function as substitutes.

Third person usage

You is used to refer to an indeterminate person, as a more common alternative to the very formal indefinite pronoun one.^[30] Though this may be semantically third person, for agreement purposes, you is always second person.

Example: "One should drink water frequently" or "You should drink water frequently".

Agreement

You almost always triggers plural verb agreement, even when it is semantically singular.

Functions

You can appear as a subject, object, determiner or predicative complement.^[5] The reflexive form also appears as an adjunct. You occasionally appears as a modifier in a noun phrase.

• Subject: You're there; your being there; you paid for yourself to be there.
• Object: I saw you; I introduced her to you; You saw yourself.
• Predicative complement: The only person there was you.
• Dependent determiner: I met your friend.
• Independent determiner: This is yours.
• Adjunct: You did it yourself.
• Modifier: This sounds like a you problem.

Dependents

Pronouns rarely take dependents, but it is possible for you to have many of the same kind of dependents as other noun phrases.

• Relative clause modifier: you who believe
• Determiner: the real you; *the you
• Adjective phrase modifier: the real you; *real you
• Adverb phrase external modifier: Not even you
