Hebrew/Yiddish term for someone/thing which is not Jewish. (See: goyish, goyische.)
"Descendants of this immigrant woman, you do not grow up in America, you and your children and their children with the goyishe names. You live in America. No such place exists. Your clay is the clay of some Litvak shtetl, your air the air of the steppes--because she carried the old world on her back across the ocean, in a boat, and she put it down on Grand Concourse Avenue, or in Flatbush, and she worked that earth into your bones, and you pass it to your children, this ancient, ancient culture and home." --Angels In America, Tony Kushner.
