People having a great time — that’s a sure sign that the occasion is festive. An awesome party, New Year’s Eve, the last day of school, Fridays: happy times where the air feels electric, that’s festive. It can also describe your mood, like when you feel full of energy and ready to dance. Sharing the same Latin root (festivus) as the words festival and feast, festive events often involve good food and great people. And a piñata always helps.
