Entertaiment is a form of recreation that involves a wide range of activities. It can be as simple as a private individual selecting from an endless array of pre-recorded entertainment; a banquet adapted for two or many; to performances designed for thousands; and on a much larger scale, as in ceremonies, celebrations, religious festivals or satire. Although the word has become strongly associated with amusement, its roots in the Medieval Latin inter tenere (to hold inside) and Indo-European root ten (stretch or expand) suggest a more serious dimension to the activity of entertaining.
