I LOVE learning Hungarian!!!! And I am doing it on DUOLINGO!
I just want to say that HUNGARIAN is my favourite language to learn at the moment. I LOVE the way they put the sentences together like they are painting pictures. It is SO much fun! And I know that the course is buggy but that's because 1) It's in Beta and 2) not many people have done it so they haven't gotten lots of other definitions in feedback yet.
They just added a bunch to the French tree and OH it is ANNOYING. FIrst of all I speak French fluently, if not perfectly and even though they let me test out level one in all the new stuff they added, I still had to spend several hours responding Bonjour Monsieur to get to the higher levels!!! Awful. But the worst part is that they mark things wrong I KNOW are right because nobody else has done that level yet and so nobody else has given them any feedback. They have ONLY one or two definitions in place!!! So don't blame HUNGARIAN or this course for their lack of other definitions. Just keep plugging away and notifying when you think they are wrong!!!
Once upon a time I tried to learn Hungarian on my own, just with books. I soon gave it up: too difficult, too strange. But now with duolingo, with the possibility to fly with the óvónők respectively to exercise over and over again, I am still learning and I like it! I am thankful for this option.
