Meaning

noun United States mathematician and founder of cybernetics (1894-1964)

noun a smooth-textured sausage of minced beef or pork usually smoked; often served on a bread roll

originClipping of wienerwurst, from German Wienerwurst (“Vienna sausage”), from Wiener (“of Vienna, Viennese”) + Wurst (“sausage”), because these sausages were originally made in Vienna, Austria. In Germany today this sausage is known as Wiener Würstchen (“small sausage from Vienna”), but in Vienna and the Netherlands it is called a Frankfurter or Frankfurter Würstchen (“small sausage from Frankfurt”).
