What is the Spanish name for the girl who celebrates a quinceañera?

The Spanish name for the girl who celebrates a quinceañera is quinceañera. The same word is also widely used for the celebration itself, so its meaning depends on context.

The term is formed from quince, meaning fifteen, with a feminine ending associated with a girl or young woman. In English-language writing, the word is usually retained in Spanish because it names a culturally specific tradition without a perfect one-word translation.

A quinceañera is often presented as entering a new stage of life, but the ceremony does not have one universally defined legal or religious meaning. Families may describe it as a coming-of-age celebration, a thanksgiving, a family blessing, or a cultural milestone.

The person celebrating may be called the quinceañera even when the event is highly personalized. Some families organize a large formal reception; others choose a small gathering, travel, or a community-focused celebration. The common feature is the fifteenth-birthday milestone.
