The Spanish term for a quinceañera’s male escort or gentleman attendant is chambelán.
A chambelán may accompany the celebrant during her entrance, formal dances, photographs, and other parts of the program. Some quinceañeras have one principal chambelán, while others have a larger court of male attendants. The exact arrangement depends on local custom and the family’s plans.
The word is related to an older Spanish term for a chamberlain or court official. In the quinceañera setting, it is a ceremonial title, not a statement that the attendant is romantically involved with the celebrant. He may be a brother, cousin, friend, or another trusted person.
The plural is chambelanes. Female attendants are commonly called damas, and sponsors may be called padrinos or madrinas. These roles can overlap in informal descriptions, but they are not identical parts of the celebration.
