Ace: The people, who are familiar with the game of Tennis, will definitely identify this very term instantly. The shot does not have any kind of difference with that of Tennis also. This is such a shot, played by the server where the receiver cannot even make contact with the racquet in reply. Though, this is used especially with reference to service, it can be used in case of other shots as well.
Alley: This term is used to indicate the area along the sidewalls. This is a common term in Squash.
Appeal: This very term is applied when a player requests to the Referee in order to consider an on or off court situation called by the referee. The term "Appeal" is normally used in all the rules of Squash, mainly in two contexts. It is used if the player requests the Referee to consider changing of a Marker's decision. It can also be used if the player requests the Referee to allow him a let. The player can appeal correctly by saying, "Appeal please" or "Let please".

Back Swing: This term is used in order to indicate a reasonable action. The primary action that a player uses in moving his racket away from his body as if he is taking preparation prior to racket movement towards the ball for contact. The Referee may consider a back swing as reasonable if it is not excessive. An excessive back swing means such a shot where the racket arm of the player is extended towards a straight-armposition.

In other meanings if the ball strikes a player before it bounces more than once upon the floor, it is also called as 'Down'. This very term is used as a Marker's call as well.
Follow-Through: This is also a reasonable term. If a player uses an action in continuing the movement of his racket after it has contacted the ball, it has called as a 'Follow-Through'. This is a reasonable action if it is not used excessively. Being used excessively, the 'Follow-Through' is such an action where the racket arm of the player is extended straightly with the racket also extending with the shaft horizontal. This action is also reasonable particularly when the extended position is maintained for other than a short period of time. The Referee may call an action as excessive 'Follow-Through' if the arm extends towards a straight position and takes a wider arc than the continued line of flight of the ball, even though the racket remains on the right vertical position. The Referee's decision is ultimate here.

However, it should be noted that when a court is constructed without the planning of such a line, i.e. the walls comprise only the playing area. If any court is constructed without part of such a line e.g. a glass back wall and the ball in play strikes part of the horizontal top surface of such a wall and deflects back into court, the ball is ruled as out. The Marker will make the decision in the normal manner if any player appeals to the Referee.

Tin: This is a very vital part of the Squash court. Situated between the board and the floor, it covers the full width of the court. It is constructed in such a manner that it makes a distinctive noise when the ball strikes it.
