A male member of a quinceañera’s court is commonly called a chambelán. The term is especially associated with the young men who accompany the honoree during formal entrances, dances, and photographs.
A court may include several chambelanes and young women, whose group performance can be rehearsed for weeks. The size and name of the court vary by country and family. Some celebrations use regional alternatives, including damas and chambelanes or other local terms.
A chambelán is not necessarily the honoree’s romantic partner. He may be a brother, cousin, friend, or another trusted participant. That distinction prevents a common misunderstanding: the court is a ceremonial group, not a set of engagements or couples.
