Pennsylvania Dutch

According to the Book Crossing Over: One Woman's Exodus from Amish Life by Ruth Irene Garrett with Rick Farrant, there is no word in Pennsylvania Dutch for love. I'm referencing page 28 of that book. Crossing over is Ruth Irene Garrett's true story about leaving the Old Order Amish Community in Kalona, Iowa. She says (and I'm paraphrasing) that when the "English" concept of love is referred to by the Amish that they use the German word for it, "liebe."
