Quinceañera is the Spanish term commonly used for the girl celebrating her 15th birthday.
The word is formed from quince, meaning fifteen, and a feminine ending related to a girl or young woman. In English-language writing, it can describe either the celebrant or, by extension, the birthday event. Spanish usage and regional speech can vary, so context determines whether the word refers primarily to the person or the celebration.
The quinceañera is usually the visual and ceremonial focus of the event. She may wear a formal gown, participate in a religious service, receive symbolic gifts, and take part in a choreographed entrance or dance. Parents, grandparents, godparents, siblings, and friends often have roles in the celebration.
The term should not be confused with madrina, which means godmother or sponsor, or dama, which commonly means a female member of the court of honor. A quinceañera is a cultural and family milestone, not a universally defined legal category.
