I was just thinking that we need a wizard school in the U.S for American witches and wizards so what do you think it would be called if there was one
There is, in fact, something like this mentioned in the 4th book, called 'Salem Institute for Witches' which somehow sounds like a girls-only school, so there probably would be something for wizards as well, and, who knows? Maybe even a co-ed one.
I think the Salem Institute probably is coed, because if you go back in history to the witch trials, the dudes who were tried for witchcraft were also called witches. Who knows, though, perhaps there is a wizard-only school or more than one witch/wizard school in the States. It's a big country
indeed. in point of fact, i don't think J(K)R has ever actually said that Hogwarts is the only magic school in the UK.
