Side on
Side on – side/direction on the field. In this case, it is necessary to understand that coordination on the playground is carried out from the point of view of a batsman (right-handed).
Consequently, the clarifications “side on” / “on side” or “leg side” (synonym) describe the area on the left or right side of the batsman’s hand standing towards the bowler.
If the batsman belongs to left-handed players (left-handed), then the part of the field to the right of him is called the “on” side, and the side, as well as leg, just change places, mirroring.
