• who is in the process of hitting the ball; or
• who, up to the point of the return reaching the front wall, has just hit the ball.

Tight length

• A term used when hitting a ball down the side wall, so that it hugs the wall, and lands in the back corner of the court

Play percentage

• A term used when referring to making no errors, but get every ball back into play. Wait for the opponent to make the error

Get to the T

• The T is really a place in the centre of the court.
  
• Literally speaking it is the junction of the Half Court line and Short Line.
  
• See Court Markings below

Attack

• During play it means to be more aggressive, take the ball on the volley, give the opponent less time, and generally force the opponent to feel rushed or threatened by your presence on the court

Play your game

• We all have a preferred way of playing, or should have a specific game plan to suit the specific opponent.
  
• Often players get influenced by their opponent's play and mirror their game.
  
• For example, if the opponent hits hard, you hit hard, if they hit soft, you hit soft - and it is easy to get sucked in

Break up the game

• When the opponent seems to be in a good rhythm, and can do no wrong, it is time to change the play.
  
• For example, one length drive, followed by a boast, followed by a drop shot, followed by a cross court lob will break up the game

Play short

• This means exactly as it says. Specifically it means bring the player to the front of the court. So hit a few more boasts and drop shots

Play long

• Hit the shots to length. For example play drives and lobs that land in the back of the court

Slow game

• Some players naturally play a slow game, which will have plenty of lobs and high serves, with a limited amount of hard drives.
  
• A slow game can also be played deliberately to upset the opponent's rhythm, or to get a "second wind"

Be patient

• To be patient, means not to try to hit a winner off every shot. It is recommended to wait till a shot is "on" before going for a quick winner

Knackered

• This is an expression used to indicate complete exhaustion

The Nick

• Where the floor meets the side wall.  When a player hits the ball into the nick, it is sometimes called a "dead nick" - a great shot.

• A line set upon the floor parallel to the side walls, dividing the back of the court into two equal parts, meeting the short line at its mid point to form the T

Out line

• A continuous line comprising the front wall line, both side wall lines and the back wall line, and marking the top boundaries of the court. In the case of a glass back wall, and the ball in play strikes part of the horizontal top surface of such a wall and deflects back into the court, such a ball is out

Quarter Court

• One half of the back part of the court which has been divided into two equal parts by the half court line
