as they couldn’t pronounce the Dutch word
I mean I can’t blame them, the language’s phonosyntactics are very different from French, it’s hard to pronounce in general and sounds awful to boot.
It’s funny how Dutch doesn’t shy away from loaning French words, despite the difference. Examples are chauffeur, etalage, cadeau, auto and medaille.
I don’t agree that aardappel is hard to pronounce in general if you’re an English speaker though. Check it out: https://en.m.wiktionary.org/wiki/aardappel
