Entertaiment is a leisure activity or form of recreation that is engaging and entertaining. It involves participation and may have a playful or humorous aspect, although it may also be serious in nature. It can be a social experience, such as parties or banquets, or a private activity, such as watching performances. Entertainment may be staged for a large audience, such as sports events or musical concerts. It can even be a part of a competition, such as the Olympic Games or the World Cup.
