Cricket

2. A score of 0
4. Another word for batsman, first used as long ago as 1773. Also something you fry fish in
7. Series between England and Australia
9. The side of the pitch which is to batsman's right (if right-handed), or left (if left-handed)
10. A ball from which no runs can be scored or wickets taken.
11. Used to mark the perimeter of the field. If the ball crosses or hits this, a boundary will be signalled
12. The ridge of stitching that holds the two halves of a ball together, and causes deviation off the pitch when the ball lands

1. A ball that reaches the batsmen without bouncing. Above waist height it becomes a beamer
3. An over where no runs that are attributable to the bowler are scored (byes or leg-byes may be scored in this over, though, as these don't count against the bowler)
5. The area of the pitch behind the batsman's legs
6. A ball that does not bounce (usually accidently) and passes the batsman at or about head height. If aimed straight at the batsman by a fast bowler, this is a very dangerous delivery (and generally frowned on)
8. A delivery that pitches too far away from the batsman and so proves impossible to score off.
