The Italian word "tedesco" for "German" has an interesting etymology that connects it to the German endonym. "Tedesco" (or "Todesco" or "Todisco") derives from the Latin word "Theodiscus," which shares the same root as the German "Deutsch." This linguistic connection highlights the historical interactions between Germanic and Romance languages. Interestingly, "tedesco" and its plural form "tedeschi" are also surnames among Italians, both in Italy and in the Italian diaspora.
