Quinceañera commonly identifies a young woman celebrating her 15th birthday.
The term is formed from quince, meaning fifteen, with a feminine ending related to the person being honored. In English-language usage, it can also refer to the entire celebration rather than only the birthday girl. Context usually makes the intended meaning clear.
Spanish usage varies by region. Quinceañera is widely recognized, while quince años may describe the event itself. In some communities, people use local family or national terminology alongside the better-known word. The male equivalent is sometimes described with a separate Spanish term, but that is not the standard label for the female celebrant.
The word does not imply that every celebration follows one script. A quinceañera may include Catholic customs, a court, a waltz, a banquet, or none of those elements. What unites the uses is the association with a young woman’s fifteenth-birthday milestone.
