1. A wide ball: If the bowler bowls the ball far away from the stumps or over the head of the batsman, the umpire will signal the ball as a wide. This gives the whole team extra run and the bowler has to bowl the ball again.
2. A duck: If the batsman gets out without scoring any run, he is said to be out for a duck.
3. An appeal: Appeal is the act of a bowler or fielder shouting at the umpire to ask if his last ball took the batsman’s wicket. Usually phrased in the form of howzat (how-is-that?).
4. A no ball: The bowler must bowl each ball with part of his front most foot behind the popping crease. If he oversteps this mark, he has bowled a no ball.
