LTI Nazis and Language
Language of the Third Reich - the commute reading. This is the famous LTI: Lingua Tertii Imperii.
Klemperer was a linguist and thus took an interest in the changes and distortions that the Nazis introduced into the German language. It's a dense book, slow to go through. Possibly more readable in the original German. I would consider this a primary sourcebook for researching fascism and its effect on culture.
