If someone could just double check my endings and cases then I'd be mighty grateful!
I also have an issue about addressing someone with a title. I know that if you're addressing someone then the noun should be in the vocative case, but if they have a title (i.e. Prince Gaius) would their title also be in the vocative to match the noun?
