A male attendant in a quinceañera court is commonly called a chambelán.
The term is used in several forms, including chambelán de honor, meaning an honored male attendant. Chambelanes may accompany the quinceañera during her entrance, formal dances, rehearsals, and photographs. In some families, the principal partner has a special role in the choreography.
Terminology varies by country and family. Some communities use escort, honor escort, or other local terms, and modern celebrations may include friends of different genders without following a traditional court structure.
A chambelán is not the same as a padrino. A padrino is a sponsor or godparent-like supporter, often an adult who helps provide an item or service for the celebration. The court, meanwhile, is made up primarily of the celebrant’s peers.
