The male celebrant of a traditional quinceañera-style fifteenth-birthday celebration is called a quinceañero.
The Spanish noun quinceañero is the masculine counterpart of quinceañera, which traditionally refers to a girl or young woman celebrating her fifteenth birthday. Both words derive from quince, meaning “fifteen,” and año, meaning “year.” The feminine form is much more widely recognized because the celebration developed primarily as a ceremony marking a girl’s transition into young womanhood.
A quinceañero celebration may include many of the same elements associated with a quinceañera, including formal clothing, a court of honor, a choreographed dance, a special meal, and a religious service in some families. Customs vary considerably by country, denomination, and family.
The word quinceañero can also describe the person rather than the event. It should not be confused with quince años, the phrase for “fifteen years,” or with quinceañista, which is not the standard Spanish term for the celebrant.
