Slaughterhouse Five- metonymy

"It was a deliberate attempt to humiliate you.  You mustn't let Jerry do things like that to you." PAGE 98

This quote is an example of metonymy.  The Germans are referred to by one common name rather than what they are.  The English men refer to the Germans all by one name.  The fact that the Englishmen call them all Jerry is effective in showing how they feel about the Germans.  The use of one name for all of them shows their disrespect for them.  It also shows that they do not feel that they deserve to be known by name.  They think what they are doing is terrible.  The name is associated with the Germans and that is how they refer to them.  The Americans are confused at first because they do not know who Jerry is.  They are not aware of the nickname given to the Germans.  I think the nickname also belittles the Germans because they are referred to as a commonplace name rather than even their nationality.  It is peaceful way for the Englishmen to show their feelings against the Germans.
