Pledge or hostage
Gyselle is a modern American spelling variant of the French name Giselle. It originates from the Germanic word 'gisil', which historically referred to a person given as a pledge or hostage to a foreign court to ensure peace. Today, the name is primarily associated with grace and elegance due to the famous 19th-century ballet.
