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.

Kartoffel is the standard German word.

Erdäpfel is used in many dialects and has plenty of variants.

Actually the various different words for potatoe and their distribution across Germany, Swiss and Austria is linguistically quite interesting (see this map [1]).

The legend is in German and roughly translates to (from top to bottom):

- Potatoes

- Ground pears

- Earth apples

- Earth pears

- Hearth apples
