Judenfrei
Judenfrei (German: [ˈjuːdn̩ˌfʁaɪ], "free of Jews") and judenrein (German: [ˈjuːdn̩ˌʁaɪn], "clean of Jews") are terms of Nazi origin to designate an area that has been "cleansed" of Jews during the Holocaust. While judenfrei refers merely to "freeing" an area of all of its Jewish inhabitants, the term judenrein (literally "clean of Jews") has the even stronger connotation that any trace of Jewish blood had been removed as an alleged impurity in the minds of Nazis.
