What is the usual Spanish term for the female celebrant at a quinceañera?

The usual Spanish term for the female celebrant at a quinceañera is quinceañera.

The word is formed from quince años, the phrase for “fifteen years,” and its feminine ending identifies the girl reaching that birthday milestone. In common English usage, quinceañera can also refer to the celebration itself, which can create two overlapping meanings.

The celebrant is the central figure in ceremonies, photographs, formal dances, and the reception. Depending on family tradition, parents, grandparents, godparents, or other relatives may play supporting roles. The event is usually designed around honoring her rather than around a standardized legal or religious status.

Quinceañera is not the same word as madrina, dama, or chambelán. A madrina is generally a female sponsor, a dama is commonly a female attendant, and a chambelán is commonly a male attendant. Regional usage can still vary.
