The usual Spanish feminine term for the girl celebrated at a quinceañera is quinceañera.
The term comes from quince, meaning “fifteen,” and the feminine ending associated with a girl or young woman. In everyday usage, quinceañera can identify the celebrant, the birthday event, or both, depending on context. English-language communities commonly use the same Spanish term.
A quinceañera is often accompanied by a court of honor. Members may be called damas and chambelanes, although names and arrangements differ across families and regions. The celebrant’s parents, godparents, relatives, and friends may also have prominent ceremonial roles.
The word should not be confused with madrina, which generally means godmother or female sponsor, or dama, which can mean a female attendant. These people may participate in the event, but neither term specifically names the girl whose 15th birthday is being celebrated.
