IPA: //ˈzwiːbæk//
KK: /ˈzwiːbæk/
A type of sweet bread that is baked, sliced, and then toasted until it becomes dry and crispy.
She enjoyed her tea with a piece of zwieback on the side.
Zwieback comes from the German words "zwei" (meaning two) and "backen" (meaning to bake). The term refers to a type of twice-baked bread, which is baked once, sliced, and then baked again to achieve a dry, crisp texture.
Think of the word 'zwei' meaning 'two' and 'backen' meaning 'to bake' — zwieback is bread that is baked twice.
