You ain't going nowhere tonight Why this sentence is considered wrong?

Answer 1

Actually, it's not "wrong," but it is not using standard English, which is the proper English you are supposed to speak at work or at school or during a job interview. There is also colloquial English, which includes slang, intentional grammar mistakes, and a very casual use of English-- this is generally used only with friends or classmates, and is sometimes heard on TV. The sentence "you ain't going nowhere tonight" contains both slang and grammar mistakes, so it is not proper English.

One mistake is the use of two negatives. In French or Spanish, two negatives are okay, but in standard English, they are wrong. So, you can't say, for example, "he doesn't have no money." In the sentence you gave, the two negatives are "ain't" (which is slang for "are not") and "nowhere." The use of "ain't" is an even bigger problem-- it is not standard English at all, and so, it must not be used. While this sentence would be understood by Americans (or people who watch a lot of movies), it would be considered wrong in its use of grammar, and wrong for using a word that is considered slang. The correct sentence would you "You're not going anywhere tonight," or "You are not going anywhere tonight."
