Another problem word is pepperoni."+ To Americans, it's a salami-like sausage, usually found on pizza. In Italy, +peperoni are bell peppers/capsicums. "Pepperoni" for sausage seems to have been coined in the US. A 1914 article says the name comes from the "peperoni" (pepper) used in making it.
I found several references that the first written use of "pepperoni" as a sausage was 1919, but no citation. I found it in a 1907 magazine article about sausage.
