What is the German 'Rad' in English?

Answer 1

"Wheel" is an English equivalent of "Rad."

Scientists are finding it increasingly difficult to pinpoint one place as the origin point for the invention of the wheel. Many people remember learning in school of the many contributions - such as the alphabet, the sailboat, the wheel, and tools - by the Sumerians to the development of Planet Earth's civilizations. But that viewpoint is being challenged by findings from improved technology and additional archaeological evidence. For example, the wheel may have begun to be used about the same time in not only Mesopotamia but also in the present areas of the Balkans, central Europe, the northern Caucasus and possibly even Mesoamerica.
