I have another question about the etymology of krůta "turkey". As you can see English attributes it to the Turks while French refers it to its origin: dinde < d'Inde < d'Inde Occidentale "from Western India i.e. the American continent".
Krůta (an older term was indián) is probably from German Truthenne/Truthahn. BTW, what is Grutte in German?
