Spanish provides the word “quinceañera” for this traditional celebration.
The word is formed from quince, meaning 15, and the feminine suffix -añera associated with a person reaching that age. In Spanish, quinceañera traditionally refers to the girl who celebrates her fifteenth birthday and is also widely used in English for the event itself.
The term is sometimes written quinceanera in English when the ñ is unavailable, but quinceañera is the standard Spanish spelling. Portuguese-speaking countries have related coming-of-age customs and different vocabulary, so the word should not be treated as a general term for every Latin American birthday tradition.
