This has actually always been something that bothered me about Hogwarts. (I'm glad someone brought it up!) It doesn't make sense not to have some sort of English class. They write so many essays for their classes, but they haven't had an English class since they were ten? I agree that a Literature class would be interesting, possibly a combined Literature/Language class.Literature- C'mon now! Who doesn't want to hear all the classics ((Just make sure not to get Hagrid and Slughorn started on 'Odo the Hero')) ? I can't imagine that all the books in Hogwart's great library are non-fiction.
I like this idea! The wizarding community is a lot smaller than the Muggle one, so it seems realistic that they would come in contact a lot more often. (Bill and Fleur?) Plus, just the fact that they can travel a whole lot easier. I also like bertiebott's Troll/Giant idea. Edit: I just realized it looks like I'm shipping the troll and the giant. >.< /editForeign and Ancient Languages- Well if Barty Crouch could do it, why not students? French ((mightve come in handy during GoF)), Bulgarian, Gaelic, Latin, Greek, ect...
I agree with bertiebott that you might need an AU warning to explain why we never saw this other teacher in the books. Unless you explain that the Ancient Runes teacher is teaching two electives (because, honestly, how many people take Ancient Runes?). Or if it is a next generation fic, it could be a new subject.
