A clean catch of the ball after it has been kicked by another player (either by a teammate or by the opposition), before it has touched the ground, or been touched by any other player, and after it has travelled a minimum of 15 metres. The term also refers to the spot on the ground where the mark or free kick took place.

定球

如果一名球员使用脚踢球的方式将球踢出，且球在空中的飞行距离超过15米，另一名球员（既可以是本方球员，也可以是对方球员）在球没有落地且没有被其他球员触碰到的情况下将球接住，那么这个球就叫做定球。

Staying ball (If it is a mark, the ball will STAY at a position and wait to be disposed)
