well, i'm a medievalist and i know Latin, French, and I can read Italian if I really try. i have no problem with the case system (except that it goes in a different order than Latin). my big problem was the vocab. i'm a lot older than the last time i started learning a whole new language, and i think i've lost the ability to master vocab quickly.

apologies to nilchance for taking over the comments! but really it's sort of topical...Jensen should totally have a facility for languages. okay, that's a stretch *g*
