What is the usual Spanish plural for a quinceañera’s male attendants?

The usual Spanish plural for a quinceañera’s male attendants is chambelanes.

Chambelanes are members of the celebrant’s formal court. They may accompany her during the entrance, participate in the traditional waltz, and perform a choreographed routine at the reception. Their clothing is often coordinated with the quinceañera’s dress and the other members of the court.

The word is especially common in Mexican and Mexican-American descriptions, but terminology varies across Spanish-speaking communities. Other regions may use different local labels for male members of the court, and some celebrations have no formal attendants.

Chambelanes should not be confused with padrinos. Padrinos are sponsors or supporters who may help finance or organize the event, whereas chambelanes are usually young participants in the ceremonial court.
