Erda

The name Erda is derived from the Old High German word 'erda', meaning 'earth'. It is closely related to the Proto-Germanic *erþō and the Old English 'eorþe', which also mean 'earth'. In Germanic mythology, Erda (or Jörð in Old Norse) is a goddess personifying the Earth. She is often depicted as the mother of Thor by Odin, making her a significant figure in the Norse pantheon.

The name gained some recognition through Richard Wagner's opera cycle 'Der Ring des Nibelungen', where Erda is a primordial goddess of wisdom and the Earth, who warns Wotan of the impending doom. This portrayal cemented her image as a powerful, ancient, and wise figure associated with the fundamental forces of nature. While not a common given name, its mythological and operatic connections give it a profound and ancient resonance.
