In Spanish, what does “quince” mean in the name quinceañera?

In Spanish, quince means fifteen in the name quinceañera.

The term quinceañera is built around the number fifteen and refers to the girl or young woman celebrating her fifteenth birthday. The related phrase fiesta de quince años literally refers to a celebration of fifteen years, although the cultural meaning is broader than a simple birthday party.

Spanish number words can cause confusion for learners because quince is an irregular-looking form rather than a word resembling English “fifteen.” The next numbers are dieciséis for sixteen and diecisiete for seventeen.

The number identifies the age traditionally associated with the event, not a fixed legal status. Families may celebrate at another time because of school schedules, travel, finances, religious calendars, or local customs. The central symbolism remains a family’s recognition of a young person’s growth.
