ペンシルベニア・ダッチ
Contrary to popular belief, the word "Dutch" in "Pennsylvania Dutch" is not a mistranslation, but rather a corruption of the Pennsylvania German endonym , which means "Pennsylvania Dutch / German" or "German". Ultimately, the terms Deitsch, Dutch, Diets and Deutsch are all cognates of the Proto-Germanic word meaning "popular" or "of the people". The continued use of "Pennsylvania Dutch" was strengthened by the Pennsylvania Dutch in the 19th century as a way of distinguishing themselves from later (post 1830) waves of German immigrants to the United States, with the Pennsylvania Dutch referring to themselves as and to Germans as (literally "Germany-ers", compare ) whom they saw as a related but distinct group.
