The glossary contains definition from many sources, including the rules of squash.
- ACE
- A shot with which the receiver cannot even make contact with the racquet; used especially with reference to service.
- ALLEY
- The area along the sidewalls. See Rail.
- APPEAL
- A player's request to the Referee
to consider an on or
off court situation. "Appeal" is used throughout the rules in two
contexts:
Where the player requests the Referee to consider varying a Marker's decision.
Where the player requests the Referee to allow a let.
The correct form of appeal by a player is "Appeal please" or "Let please".
- ANGLE
- Any shot which hits a sidewall before hitting the front wall.
- AROUND
- See Coming Around.
- ATTEMPT
- The Referee shall decide what is
an attempt to play the ball. An attempt is made, when in the opinion of
the Referee, the striker has moved his racket towards the ball from the
backswing position.
- BACKING ON THE BALL
- Backing up from the sidewall, especially on service, to take a ball that is coming out far from the side and/or backwall.
- BACKSPIN
- See Spin.
- BACKSWING
- (REASONABLE) The initial action used by a player in moving his racket away from
his body as preparation prior to racket movement towards the ball for
contact. A backswing is reasonable if it is not excessive. An
excessive backswing is one in which the plauer's racket arm is extended
towards a straight arm position and/or the racket is extended with the
shaft approximately horizontal. The Referee's decision on what
constitutes a reasonable as distinct from excessive backswing is final.
- BACKWALL SHOT
- A shot that hits the backwall and a sidewall (in either order) before reaching the front wall.
- BOARD
- The lowest horizontal marking on the
front wall, with the tin beneath it covering the full
width of the court.

- COMING AROUND
- (also called Turning on the Ball) Making a 180-degree turn from one's forehand to backhand (or vice versa) to take a ball that is rebounding out from a sidewall or a backwall. The player alerts his opponent of his intent by saying "around" or "coming around."
- CORNER
- Any shot that hits a sidewall close to the front wall and then hits the front wall. See Reverse Corner.
- CROSS COURT
- A front wall shot that makes a "V" shape and lands in the opposite side of the court from which it was played, in mid-court or deeper.
- CUT
- See Spin.
- CUTLINE
- A line upon the front wall, 50 millimeters (2 inches) in width, the top edge of which is 1.83 meters (6 feet) above the floor and extending the full width of the court.
- DIE
- When a ball fails to bounce or come out because it has been hot with great touch, underspin, or has hit the nick.
- DOUBLE BOAST

- FOLLOW-THROUGH
- (REASONABLE) The action used by a player in continuing the movement of his
racket after it has contacted the ball. A follow-through is reasonable
if it is not excessive. An excessive follow-through is one in which the
player's racket arm is extended towards a straight arm position with the
racket also extended with the shaft horizontal - particularly when the
extended position is maintained for other than a momentary period of
time. And excessive follow-through is also one in which the arm
extended towards a straight position takes a wider arc than the
continued line of flight of the ball, even though the racket is on the
correct vertical position. The Referee's decision on what
constitutes a reasonable as distinct from excessive follow-through is
final.
- FOOT FAULT
- A serve that is unacceptable because the server's foot was not totally inside the service box up to the point at which contact was made with the ball.

the out line or 3) in addition to 1) and 2) on courts which are not
fully enclosed the ball has passed over the out line and out of the
court without touching any wall or, if no out line is provided, passed
over any wall and out of the court. ("Out" is also used as a Marker's
call).
- OUT LINE
- A continuous line comprising the front wall line, both sides wall lines and the back wall line and marking the top boundaries of the
court. Note: When a court is constructed without provision of such a
line, ie. the walls comprise only the area used for play, or without
part of such a line (eg. a glass back wall) and the ball in play strikes
part of the horizontal top surface of such a wall and deflects back into

manner by the Marker, subject to appeal to the Referee.

- SIDESPIN
- See Spin.
- SLICE
- See Spin.
- SLOW ANGLE
- An angle shot that strikes the sidewall in mid- to backcourt.
- SPIN
- The rotation of the ball in flight, which is imparted by the point on the ball contacted by the racquet, the angle of the racquet face at the time of contact, and the direction of the racquet during the swing.
Underspin (or backspin, or cut), which causes the ball to rotate backward for the direction in which it is travelling, is the most common type of spin in squash. It is basically imparted by an open-face racquet contacting the ball slightly on the underside, and the result is that the ball stays low and dies after contacting the front wall.
Sidespin or slice, which gives the ball a sideways rotation during its forward flight, is used mostly in touch shots. It is basically imparted by contacting the ball slightly to either side and drawing the racquet across the ball in the opposite direction from the point of contact with an open-faced racquet. The result is that the ball will bounce slightly sideways opposite from the predictable direction.
Topspin is used very little in squash, save in the hard serve. It is imparted by coming over the ball with a closed racquet face.
- STRIKER

hit the ball after it has rebounded from the front wall, or who is in the

- The gain achieved by the player who
wins a rally, either in the course of play or on award by the Referee,
and which results in either the scoring of a point or change of hand.
