Swanhilde is a variant of the name Swanhild, which is of Old Norse origin. The name Swanhild itself is derived from the elements 'svanr' meaning 'swan' and 'hildr' meaning 'battle'. In the context of the ballet 'Coppélia', Swanhilda is the principal character, a young woman who is central to the narrative. The name Swanhilde, therefore, carries connotations of grace and strength, much like the swan, a symbol of beauty and elegance, combined with the valor of a warrior.
