Entertaiment is a category of things that can be perceived to be amusing, humorous or enjoyable by some people and not by others. Entertaiment can be found in movies, television shows, novels, poetry, music and other media. The word comes from the Medieval Latin intertenere, a compound of the prefix inter- meaning “inside” and the suffix tenere, derived from the Indo-European root ten, which means to hold or stretch something. It is noteworthy that many forms of entertainment have the ability to cross between various media and that they tend to recur in the form of familiar images, themes and structures.
