The term 'START OF A TENNIS POINT' can be broken down into two crossword solutions: TOSS and SERVE. In tennis, the start of a point is initiated by the server tossing the ball into the air and then hitting it over the net in a SERVE. The SERVE must land within the boundaries of the court and must not touch the net. If the SERVE is successful, the point begins and the players rally until one player fails to return the ball or commits a fault.
