Tennis, original name lawn tennis, game in which two opposing players (singles) or pairs of players (doubles) use tautly strung rackets to hit a ball of specified size, weight, and bounce over a net on a rectangular court. Points are awarded to a player or team whenever the opponent fails to correctly return the ball within the prescribed dimensions of the court.

The addition of color and style to tennis wear (once restricted to white) created an entirely new subdivision of leisure clothing. Racket frames, which had been of a standard size and shape and constructed primarily of laminated wood, were suddenly manufactured in a wide choice of sizes, shapes, and materials
