German has 2 words for the fruit orange. Orange (obviosuly) and Apfelsine.
"The Low German word is Appelsin (from where it spread to Danish and Norwegian). It is therefore clear why a Northern German would regard Apfelsine as popular and Orange as posh. I suspect the origin is Dutch where appelsien is a variant of sinaasappel (Chiana apple)." - https://forum.wordreference.com/threads/apfelsine-vs-orange.1329938/
