Do you perchance know the term equivalent to “Polack” for Germans? I have been casting around for it, but keep failing.
In Polish I was amused to find out that the word for Germany: Niemcy and the word for a German: Niemiec are derived from the word nem meaning "mute" -- its similar in other Slavic languages -- presumably the early Slavs came upon the Germans saying "ach, die zu" and went "Eh? What are you saying? are you unable to speak?" :-P
