Is this english sentance correct?
"You dont know nothing !"
I find this sentance in a american TV-series. That is logically odd to me, because that's a double no. Shouldnt this mean "You know everything" ?
What is the difference bewteen "You dont know nothing !" and "You dont know a thing/anything !" or "You know nothing ! (jon snow, haha) " ?
Thanks in advance!
