Hello everybody, Frequently we have the chance to use tag questions in daily conversations, or if not, at least the chance to learn what it is about through grammar books. Nevertheless, out of the blue, I've remembered that never have I seen or heard tags questions for the verb there to be. Let us say: There is a mistake, isn't there? There is not any cars, there is? Are these things possible or just an absurd? Is there any tag question for the verb there to be at all? Thanks in advance!
