Shvartzah
I must correct you, it is not a word that Jews use, true it does mean a black person, but it is not derogatory or anything like it. Shvartzah just means a black person in Yiddish. And just because it's Yiddish doesn't mean that all Jews say it.
Person 1: Gai shlog dein kup en vant! (who is that man over there?)
Person 2: Vie Chavele tsu der shvartzah (oh, he's just a black man)
