A Finn here, Finnish is not indoeuropean language so apart from loan words it IS completely different. A very different grammar, a lot of weird words and so on.
Watched a video today - its a series where they have students from different countries comparing their languages... English Friends or something? Anyway, the one i watched had students from the Uraligic(?) branch - Estonian, Finnish, and Hungarian, and they found some things they could understand while others were at a complete loss.
