Entertaiment is a word that describes agreeable occupation for the mind; diversion; amusement: e.g. solving the daily crossword or attending a theatrical performance. It also can refer to a formalized activity, such as a ceremony, celebration, religious festival or satire. Entertainment has evolved over time to encompass a wide range of activities and can be scaled to any size, from an intimate affair that requires no more than two people, to an event intended for thousands.
The word derives from the Latin intertenere, or “to hold inside.” The suffix -ment has come to mean something relating to pleasure or amusement. Entertainment often hits on themes that our brains were evolutionarily shaped to react deeply to, such as social backstabbing and murders. This can result in the stimulation of the release of seratonin and dopamine.
