Entertaiment is one of those words that gets abbreviated to “entmt” on fliers and in some industry news publications when space is limited. It is also used to refer to a specific type of entertainment such as a concert or a casino.
Some forms of entertainment are powerful enough to inspire a retelling in another medium, such as the story of Scheherazade in the Persian professional storytelling tradition which was turned into an orchestral work by Rimsky-Korsakov, a film by Pasolini and an innovative video game.
