The term 'Area of Action' can be broken down into two words, 'ARENA' and 'FIELD'. ARENA is a Latin word meaning 'SAND' or 'open space', and it is often used to refer to an enclosed area used for sports or entertainment. FIELD is a word that has many meanings, but in this context it refers to an area of land, usually used for agricultural purposes. Together, these two words form the phrase 'Area of Action', which can be used to describe any area where activities take place. This could include a sports ARENA, a FIELD of crops, or any other area where people are actively engaged in some kind of activity.
