What is a male celebrant of a traditional quinceañera commonly called?

A male celebrant of a traditional quinceañera is commonly called a quinceañero.

The feminine noun quinceañera traditionally identifies a girl celebrating her fifteenth birthday, while quinceañero is the corresponding masculine term. The distinction is linguistic as well as cultural, because the celebration’s customs have historically focused on girls reaching this milestone.

A quinceañero may participate in many of the same elements associated with a quinceañera, including formal clothing, a court of attendants, a religious service, a family reception, and choreographed dancing. The exact format depends on the family and community.

Quinceañero should not be confused with chambelán. A chambelán is typically a male attendant or escort in the court, not the name for the birthday celebrant. Likewise, damas are female attendants, making the terms describe different roles in the ceremony.
