Diether

Diether is a Germanic given name composed of two Old High German elements: theod, meaning people or folk, and heri, meaning army or warrior, giving the name an overall sense of warrior of the people. It belongs to the large family of Germanic dithematic names built on these same roots, which were widely used among the medieval nobility of the Holy Roman Empire. Closely related forms include Dietrich, Theodoric, and Dieter, all of which share the theod element.
