How did words ending on -tion like Operation, Information, or Kommunikation enter the German language? Do these words come from English or French? Or were they first brought to English then to German?
I'm asking this because I saw an article saying that words ending on -tion in English all come from French. Since many German words also end on -tion, (and they don't really look like to have originated in German,) I begin to wonder where do those words come from.
