I would love Duolingo to offer Latin, as so many technical, legal, medical and scientific words in most modern European languages derive from Latin. It really would be a huge help.
ange1tears2 is right about the dearth of Latin webpages not suiting duolingo's purpose. But still, Latin on duolingo would be great for new learners or people who wish to review. It would be right after Russian in my list of "wants," here. But it won't happen soon, I bet.
Marvelous! That would be great. Let´s hope duolingo okays this soon. . . . [added] Russian-English has been approved and implemented, so far in beta. It's working out great, and there's no reason Latin should be any different. Both languages being inflected there are many similarities, and Russian seems to work fine here.
