The Spanish masculine counterpart of quinceañera for a boy’s fifteenth-birthday celebration is quinceañero.
Quinceañero is formed from the same quince- root as quinceañera, with the masculine ending -ero. It can describe a male honoree or a celebration marking his fifteenth birthday. In English-language communities, quinceañera is still sometimes used broadly for the tradition, even when the honoree is a boy.
The custom is often presented as a girls’ coming-of-age tradition, but boys may also have fifteenth-birthday celebrations. Names, rituals, clothing, and religious elements depend on local culture and the preferences of the family.
This vocabulary distinction is separate from the word chambelán, which identifies an attendant or escort in a court. Quinceañero identifies the celebrated person, not a supporting member of the ceremony.
