From Latin *festa* (plural of *festum*, "holiday, feast"), derived from *festus* ("festive, joyful"), related to *fanum* ("temple, sacred place"). The word entered Portuguese largely unchanged, retaining its sense of communal celebration.

Festas are central to Brazilian life. Brazil is home to some of the world's most famous celebrations — Carnaval being the most iconic — but everyday festas (birthday parties, neighborhood get-togethers, and religious festivals like Festa Junina in June) are equally important to social bonds. The phrase *ir para a festa* (to go to the party) is among the most common social invitations you'll hear.
