You is the plural form of the second-person pronoun. In the past, you was used only in the dative case, but now it is used in all cases and numbers. When speaking to someone, you are the second person in the conversation. This pronoun is also used when the subject has not been identified. In this case, you would say, “My name is John.”
The word you embodies the dark side of obsession. It is often shortened to “you,” which is often used in a sarcastic manner to imply a sense of trust. This shows how easy it is for someone to invade your privacy. While the character in “You” is quick-witted, he is not entirely trustworthy, and his sarcasm makes him seem believable. The movie illustrates how easily people’s privacy can be invaded.
In the series, Joe Goldberg, a bookstore manager, obsesses over Guinevere Beck, a graduate-school student. His obsession soon turns dangerous. Netflix recently picked up the series, and the second season of the show is already in the works. The movie is directed by David Fincher, who wrote the book. You is a highly recommended read. However, be warned: this show is a bit disturbing if you’re looking for a good time.
The use of you has been expanded in the United States, with additional forms developed to distinguish the singular and plural. In the South Midland, you-all is widely used in informal speech, and y’all is common outside of this region. You-uns and you-all are also commonly used in nonstandard speech. The South Midland forms of you-all are particularly pronounced and use this form for the second person singular. If you are unsure which form is most appropriate for your speech, you can consult an English dictionary or ask someone who can translate it for you.
