1.Bowled: the bowler has hit the wicket with the ball and the wicket has "broken" with at least one bail being dislodged (note that if the ball hits the wicket without dislodging a bail it is not out).
2.Caught: the batsman has hit the ball with his bat, or with his hand which was holding the bat, and the ball has been caught before it has touched the ground by a member of the fielding side.
3.Leg before wicket (lbw): first and foremost, the ball must, in the opinion of the on-field umpire, be going on to hit the stumps if the ball had not hit the pad of the batsman first. If the batsman plays an attempted shot to the delivery, then the ball must hit the batsman's pad in line with the stumps and be going on to hit the stumps for the batsman to be given out. If the batsman does not attempt to play a shot, then the ball does not have to hit the pad in line with the stumps but it still must be going on to hit the stumps. If the ball pitches outside the leg stump, then the batsman cannot be given out under any circumstances.
4.Run out: a member of the fielding side has broken or "put down" the wicket with the ball while a batsman was out of his ground; this usually occurs by means of an accurate throw to the wicket while the batsmen are attempting a run.
5.Stumped is similar except that it is done by the wicketkeeper after the batsman has missed the bowled ball and has stepped out of his ground, and is not attempting a run.
6.Hit wicket: a batsman is out hit wicket, if he dislodges one or both bails with his bat, person, clothing or equipment in the act of receiving a ball, or in setting off for a run having just received a ball.
7.Hit the ball twice is very unusual and was introduced as a safety measure to counter dangerous play and protect the fielders. The batsman may legally play the ball a second time only to stop the ball hitting the wicket after he has already played it.
8.Obstructed the field: another unusual dismissal which tends to involve a batsman deliberately getting in the way of a fielder.
9.Handled the ball: a batsman must not deliberately touch the ball with his hand, for example to protect his wicket (note that the bowled ball often hits the batsman's hand while it is holding the bat but this is not out; though he can of course be caught off his hand).
10.Timed out usually means that the next batsman did not arrive at the wicket within three minutes of the previous one being dismissed.
