Entertaiment is the activity of entertaining; something that amuses, delights, or interests people. It can be as simple as playing a game of online poker in the comfort of your own home, or as elaborate as a theatrical production intended for thousands. Entertainment is often a source of pleasure, but it can also serve other purposes: ceremonial, social, religious, or satirical for example. The word entertain comes from the Latin inter tenere, with the prefix inter meaning “inside” and the suffix tenere derived from the Indo-European root ten, meaning to hold or stretch out.
