Yesterday I saw a headline in a German newspaper using the word 'Kop' and yes, they were writing about policemen.
Okay, I don't read much in German but I have not seen the usage of the word 'cop' and especially not the Germanified version 'kop' before. Is this common?
Normally, when English words make it into the German language, their original spelling is kept, but under what circumstances is it changed?
