Entertainment is a type of art or performance. It is an activity that involves the creative imagination, skill and talent. It can be in a variety of forms, including theatre, film, music and dance. It can also be an active activity such as sports or games. It can also be an activity that provides a social outlet such as partying or a rite.

Some activities, such as hunting or war, that were once part of entertainment, have become spectator sports.

You can abbreviate entertainment to entmt on a flier or in industry news publications, but this is rare in general prose.
