I learned Hungarian as a Mormon missionary, and by far this agglutination (I'd never seen that term before) is my favorite part of the language. It's like being given a set of word legos and told "go nuts!" And it always seemed really regular to me; I was never as frustrated learning Hungarian as I was with German in high school.

We taught English classes there, which helped me realize just how capricious the language can seem to an ESL student.
