From the clown at your child’s birthday party to Broadway shows and stadium rock concerts, entertainment is anything that amuses or distracts us. It may be a theatrical performance, a visual distraction such as a picture or video, or audio entertainment like music. It can be a form of education or a means to achieve insight or psychological growth, but it is often simply fun and frivolous.
Entertainment is sometimes abbreviated to entmt, particularly on fliers or in industry news publications when space is at a premium. However, it is rarely abbreviated in general prose.
