Die theater / die party
Hello, everyone! Pardon my ignorance, but could anyone tell me what a “die theater” or “die party” mean? There’s no context. It’s just a phrase from a grammmar book. (I went to die party last night). So, maybe it’s a misprint? And they intended just the article “THE”? I did not find anything on the Net, they suggest that it’s German!!! (’die’ is an article in German), so who can explain it, please? Thanks to everybody.
