A quinceañera’s formal male escort is often called a chambelán in English-language descriptions.
A chambelán may be a member of the court of honor who accompanies the honoree during formal portions of the celebration. He can participate in the entrance, photographs, presentation, and choreographed vals. In some families, one principal escort has a more prominent role; in others, several chambelanes share the duties.
The term comes from Spanish usage connected historically with the word chamberlain. At a quinceañera, it is a ceremonial label rather than a title of nobility. The role also should not be confused with padrino, which refers to a sponsor or godparent and may involve financial or organizational support.
Customs vary across countries and families. Some celebrations use a court made entirely of friends, some include both male and female attendants, and some have no formal escort. “Chambelán” is therefore a traditional term, not a required feature of every quinceañera.
