Entertaiment is the enjoyment of an activity which involves play, especially in children. It is often taken as a synonym for amusement, but entertainment may have a deeper significance such as the performance of ceremonies and celebrations, or a serious political, social or moral message, including satire. It is often a social activity which brings people together, and can involve a wide range of activities from cooking and dining (either for two, or for a large audience), through to dance, music, theatre and games. Entertainment evolves, but some forms remain relatively stable, for example story telling and the use of music and dance in traditional societies.
