The French term for potatoes is also ‘earth apple’: pomme de terre

I'm fairly sure that is the origin of Erdäpfel. We certainly thought this was a funny name for potato when we learned French in Scotland :-)

When I learned German the word for potato was Kartoffel.

I suppose this "earth apple" formulation coming up in several languages is partly because potatoes are from the New World, and Old World languages won't have a "traditional" word for them. Whereas in English it's basically a loanword.

  • It also makes more sense when you realize that 1) pomme in older French meant fruit generally, not apples specifically, and 2) sweet potatoes were introduced to Europe well before white potatoes were. So "earth fruit" seems fitting.

    • Technically apple is also just the general term for fruit from its root in Proto-Indo European, ab(e)l.

    • Do you have more detail about your second point?

      Since they both come from America, sources I can find place them in Europe during the XVIth century.

In Chinese one word for potato is "earth bean" 土豆 (the other word is "horse bell tuber" 马铃薯)

french fries are pommes frites. the french term is also used in germany (though sometimes shortened to pommes or fritten).

Diverging but funny: "pommes de route" is a french-canadian colloquialism for horse droppings (on the street - "road apples")
