Entertaiment is an idea that has come to be associated with fun and laughter, although many entertainments have a serious purpose. For example, the experience of seeing a play or other performance may be one form of learning how to understand a culture or society. The activity of solving a crossword puzzle, for another example, can be entertaining or may serve as a means of keeping the mind active and focused. Entertainment can be adapted to almost any scale or type of audience, from a private enjoyment, such as watching a video or playing games, to performances intended for thousands or even a global television audience. You can sometimes abbreviate the word entertainment to entmt on a flier or in industry news publications, but it is not common in general prose.
