Do you know Paradeiser?
I thought that is a word mainly used in Austria, though the tomato at times is also called Paradiesapfel, I haven't heard the word in a long time.
The word in standard Hungarian (paradicsom) and Slovenian (paradinik) are the equivalents of Paradeiser (e.g. shortened versions of 'paradise apple'). So it seems to be a cultural tradition that is both multilingual, and only regional within the state it emerged in (the Habsburg Empire). *Lunatic*, n. One whose delusions are out of fashion.
