Moin, Servus or Grüezi (“hello!” in North Germany, Bavaria/Austria, and German-speaking Switzerland respectively)? Möhre, Karotte or Rüebli (regional words for “carrot”)? Is it die or das Mail (“email”)? All these words and forms are correct. And they are expressions of how varied the German-speaking world is, both linguistically and culturally – a reality that ought to be reflected in German teaching. But how to go about it?
