What term describes the girl celebrated at a quinceañera?

The girl celebrated at a quinceañera is called the quinceañera.

The same word is also widely used for the celebration itself, so context determines whether it means the person or the party. In the most direct sense, the quinceañera is the girl reaching her fifteenth birthday and serving as the event’s central honoree.

She may be accompanied by parents, relatives, godparents, and a court of honor. Depending on family custom, the program can include a formal entrance, a religious service, a waltz, speeches, photographs, and a reception. None of those individual features is required in every modern event.

The term is feminine Spanish grammar. A male celebrant may be called a quinceañero, while a male court attendant is commonly called a chambelán. Those distinctions prevent a common mix-up between the honoree and the people who accompany the honoree.
