WHAT DIALECTS.

No it's not. Double negative works in other languages, e.g. Polish, Spanish, but is considered incorrect in English, as it makes a positive.

Litotes are the exception - when they are used, they are not considered incorrect

@serosenpai say 'which'. ;)

WHICH DIALECTS

@shiftingsands in standardised English, you are correct. There are plenty of dialects in which a double negative is the correct and sometimes only correct way to express a negative, and it has been for hundreds of years. I don’t know exactly which dialects, but I would expect maybe some very northern English dialects

Yes, standardised English, which is the correct form of English. Anyone who uses a double negative is nonstandard. Which means doesn't conform to the usual rules, making it incorrect. In that case, that would mean other nonstandard instances would be considered correct just because it is commonly used in a 'dialect'. E.g. Although a lot of people may say 'I done that', it is an incorrect form and not proper English.

If we’re talking about prescriptive grammar, yes. However, I am talking about descriptive grammar, which is how people actually speak. While the prescriptive grammar (which is used to define “proper English) is the same for all dialects, the descriptive grammar varies quite a bit.

Well the person in this post was not speaking. It's written as a text (although even if she were talking, it'd be grammatically incorrect)
