[schoen]

I know Hungarian doesn't normally have any Indo-European roots, but it can of course borrow words from neighboring languages, so I would have wondered whether váltás could have be borrowed from a Romance language, from the same root as volte/volta (from Latin volvo), meaning 'turn' (particularly given the possible cultural influence of German Wende, which we were just discussing).

I checked on Wiktionary and this nice theory is not right; váltás has been traced back to Proto-Finno-Ugric roots and has known cognates in other distant Uralic languages. Oh well! At least we live in a miraculous time where one can easily check etymologies in various language families in five seconds. :-)

But amusingly, "revolution" itself also literally etymologically means ... turn!
