Umvolkung
Umvolkung (German: [ˈʔʊmˌfɔlkʊŋ]) is a term in Nazi ideology used to describe a process of assimilation of members of the German people (the Volk) as a way for them to forget about their language and their origin. As a neologism, it echoes Umpolung, 'polarity inversion', leading to an interpretation akin to "ethnicity inversion".
