The Spanish word quince, meaning fifteen, helps form the name quinceañera.
Quince is the age at the center of the tradition, while the ending -añera is connected to the Spanish word año, meaning year. Together, the name points to a fifteenth-year milestone. Spanish spelling uses the ñ in quinceañera, and the related word quinceañero is commonly used for a male celebrant.
The celebration’s name is therefore descriptive rather than the name of a particular saint, dance, or garment. Families may give the event religious, secular, or strongly regional features while retaining the same age-based name.
English speakers sometimes omit the accent mark or replace ñ with n in informal writing. The standard Spanish spelling is quinceañera, with both the ñ and the acute accent on the final a.
