Aren't is a contraction and means are not. You could have googled that in less time than it took to post your comment.
Do you seriously think my question was about english?
What was it about?
Yes, What else could it possibly have been about? You don't seem to be a native English speaker, so I thought you didn't understand what "aren't means.
It's a bit curious that you haven't answered my original question, or come back with anything substantive apart from expressing surprise at someone not understanding what you meant by "Aren't?"
