Bertha

Bertha is a female Germanic name, from Old High German berhta meaning "bright one". It was usually a short form of Anglo Saxon names Beorhtgifu meaning "bright gift" or Beorhtwynn meaning "bright joy".

The name occurs as a theonym, surviving as Berchta, a figure in Alpine folklore connected to the Wild Hunt, probably an epithet of *Frijjō in origin.

Bertha appears as a Frankish given name from as early as the 6th century. The monothematic Bertha as a given name may, however, not originate with the theonym but rather as a short form of dithematic given names including the "bright" element. This is notably the case with the mother of Charlemagne, Bertrada (properly berht-rada "bright counsel") called "Bertha Broadfoot." Carolingian uses of the name Bertha, as in the case of Bertha, daughter of Charlemagne and Bertha, daughter of Lothair II, are in this tradition.

In modern times, the name is associated with an unusually large example of a class of objects. Many large machines are nicknamed Bertha for the World War I howitzer known as Big Bertha.
