That´s the correct answer, eno - well done!

"Purjelentokone" is actually a combination of three words: "purje" means a sail, "lento" means flying or a flight and "kone" means a machine, so "lentokone" is the finnish word for "airplane".

I´d like to know what method did you use to find it out? I mean, I didn´t put up that challenge to brag off or anything like that, but I must admit that I am a bit jealous of all you native english-speakers. You can go just about anywhere on this planet and you´ll always get along fine using your own language. So I figured it´s just fair to make you puzzle about a really strange language for once.

For some reason I´m so curious that I keep studying different languages all the time - I may never learn them so well, but I sure do get good service in all the bars abroad!

PS. By the way "eno is the finnish word for an uncle from the mother´s side of family.
