FESTAL is a term that can be used to describe a FESTIVE or GALA event. It is derived from the combination of two words, 'FESTIVE' and 'GALA', which both refer to a celebratory occasion. FESTIVE events are typically characterized by joyous music, decorations, and food, while GALA events are usually more formal and elegant. Together, these two words create a term that encompasses both the joyous and formal aspects of a celebratory event.
