Kick-off is a place-kick from the centre of the field of play.
Kick-out is a drop-kick, or place-kick, by a player of the side which has touched the ball down in their own goal, or into whose touch-in-goal the ball has gone.
In touch means out of bounds.
A fair is putting the ball in play, from touch.
A foul is any violation of a rule.
A touch-down is made when the ball is carried, kicked, or passed across the goal-line and there held, either in goal or touch-in-goal.
A safety is made when a player, guarding his goal, receives the ball from a player of his own side, and touches it down behind his goal-line, or carries the ball across his own goal-line and touches it down, or puts the ball into his own touch-in-goal.
A touch-back is made when a player touches the ball to the ground behind his own goal, the impetus which sent the ball across the line having been received from an opponent.
A fair catch is a catch made direct from a kick by one of the opponents, provided the catcher made a mark with his heel at the spot where he made the catch.
Interference is using the hands or arms in any way to obstruct or hold a player who has not the ball.
