Entertaiment means to amuse and distract. From the clown at a birthday party, to Broadway, stadium rock, or your friends fighting over the last potato chip, entertainment takes many forms. It can be visual (a show or a painting) or aural (songs and music) or tactile (sports or games). It also may involve food and drink.
The word is often abbreviated to entmt on fliers and industry news publications in which space is at a premium. However, it is rarely abbreviated in general writing.
