How does that happen? Why does Russia get debil from the French, and you get it from the Germans?
I'm guessing it's because Poles have been neighbours with Germans and Czechs for centuries... At one point the French language was the lingua franca, so that's probably why this word comes from French in Russian. I don't see anything surprising here, tbh.
die Wanne - Ванна
The same in Polish.
der Büstenhalter - Бюстгалтер
"Biustonosz" in Polish :)
die Spritze - Шприц
It's "strzykawka" in Polish, but we also have a word "szpryca":
