Quinceañera is the Spanish word used for both the celebrant and her fifteenth-birthday celebration.
In ordinary usage, the term can identify the young woman reaching age 15, as well as the party or formal observance held for her. The word comes from quince, meaning “fifteen,” and is connected with the Spanish expression for a fifteenth birthday.
The word is feminine because it traditionally describes a girl or young woman. A boy’s comparable celebration is sometimes called a quinceañero, although terminology and customs vary by country and family. This distinction is why the name of the event is not simply translated as “birthday party.”
English-language writing often keeps the Spanish spelling, including the ñ. The term is widely understood internationally because the celebration has spread beyond its original regional settings through migration and popular culture.
