In Hungary we don’t even have a separate name for 11 and 12, just 10 + 1 and 10 + 2. But at least we messed up the billions, it’s called ‘milliárd’ and the trillion is ‘billió’. We were so close to making it perfect.
I think that’s fairly normal in Europe, isn’t it? In Germany we have Million, Milliarde, Billion, Billiarde instead of million, billion, trillion and so on, too.
