For some reason the article chose to use Estonian as an example of Finno-Ugric languages, which have all been traditionally considered difficult for English speakers.

Finnish and Hungarian definitely have their place amongst the hardest languages to learn. If I'm not mistaken, Hungarian has 22 cases of declension.

Hungarian is even difficult for other Eastern Europeans. I have yet to meet anybody that speaks Hungarian, that is not actually Hungarian.

Amerikai vagyok, de Magyarul tudok beszélni. A nyelv lego-hoz hasonlit - kis kockákkal építsz szavakat. Szeretem.

I'm American, but I can speak Hungarian. The language is like legos. You build words out of little blocks. I love it.

I am hungarian and I met several people in Hungary coming from all over the world, who somehow fell in love with the country or the language and did learn the language quite well.

So it can definitely be done (as with any other language), although you need strong motivation and a bit love of the language. But I think there are not many people in the world who has the motivation for learning an obscure language that is only spoken in one Eastern European country.

I started learning it about 6 months ago, and was in Hungary from July - September. The language immersion helped me a lot....no one speaks English in Magyarorszag :).
