What is the usual Spanish term for the girl celebrating a quinceañera?

The usual Spanish term for the girl celebrating the milestone is quinceañera.

The noun is feminine and is formed from quince, meaning fifteen, with a suffix identifying a female celebrant. In everyday usage, quinceañera can refer to the girl herself or, depending on context, to the celebration organized for her.

The same word is often used in English-language discussions of the tradition. This can create a small ambiguity: a sentence may describe a quinceañera as a person, a party, or the entire cultural custom. Context normally makes the meaning clear.

The term should not be confused with damas or chambelanes. Those words identify members of the celebrant’s court or attendants, not the central birthday celebrant.
