The title for the heir to the French throne; in modern usage, any person designated as the successor or heir to leadership.
From French 'dauphin,' originally a geographical name (Dauphine region), that became a title. The symbol was a dolphin, and 'dauphin' comes from Latin 'delphinus' meaning 'dolphin,' which also decorated the coat of arms.
The most famous dauphin was the young 'Lost Dauphin' Louis-Charles, imprisoned during the French Revolution and possibly spirited away—his mystery captivated history for centuries with claims he escaped to America as a secret royal heir.
Dauphin (heir to French throne) was exclusively male by inheritance law and custom. The feminine form 'dauphine' was only used for wives of dauphins, not daughters as heirs.
Use 'heir' or 'crown prince/princess' in modern contexts to avoid gendered succession assumptions.
