Behind the scenes
The word "exterminieren", which the German-speaking Daleks used, is not commonly used. In classic dubs of Doctor Who, Daleks shout "vernichten" (meaning "to kill off"), whereas in modern dubbing, the verb "eliminieren" is used, meaning "to eliminate".

The full dialogue for the German Daleks is as follows: "Exterminieren! Exterminieren! Halt! Sonst werden wir Sie exterminieren! Sie sind jetzt ein Gefangener der Daleks! Exterminieren! Exterminieren!" This translates as: "Exterminate! Exterminate! Stop! Or we will exterminate you. You are now a prisoner of the Daleks. Exterminate! Exterminate!"
