What Spanish name is commonly used for a girl celebrating a quinceañera?

The girl celebrating a quinceañera is commonly called the quinceañera.

The term is also used for the celebration itself in English and Spanish. In Spanish, quinceañera is the feminine form associated with quince años, meaning “fifteen years.” The ñ is important: it is a distinct Spanish letter, not simply an n with decoration.

A quinceañera may be accompanied by a court, family members, and sponsors or godparents. Depending on local custom, members of the court may be called damas and chambelanes, although terminology and participation differ between families and countries.

The word should not be confused with madrina, which generally means a female sponsor or godmother, or with dama, which can refer to a female member of the court. Those terms describe participants or roles; quinceañera identifies the central celebrant.
