tenisie

Tenisie, or tennis in many languages, is a racquet sport played between two players (singles) or four players (doubles). It is played on a rectangular court divided by a net, with players using a stringed racquet to hit a felt-covered ball over or around the net, aiming to land the ball in the opponent's court in a way that they cannot return it. The game emphasizes speed, stamina, technique, and tactical positioning, and is organized at amateur and professional levels worldwide.

Modern tennis originated in 19th-century England from lawn tennis. Major Walter Clopton Wingfield patented a portable version in 1874 under the name Sphairistikè, which evolved into the standard game of lawn tennis. The first Wimbledon Championships were held in 1877, and the sport soon spread globally. The International Tennis Federation (ITF) governs the rules and structure of international competition, while professional tours for men and women are run by the ATP and WTA, respectively.

Equipment includes a racquet with a strung frame, a felt-covered ball, and appropriate footwear. The court types vary: grass, clay, hard (acrylic or asphalt), and indoor carpet. The net sits at 0.914 meters at the center and spans the width of the court.

Scoring follows the sequence 0, 15, 30, 40, game, with ties at deuce and advantage as needed. A standard set is won by the first player to reach six games with a margin of two; if 6-6 is reached, a tiebreak is usually played. Matches are typically best-of-three sets for women and most men; men's Grand Slam matches are best-of-five sets.

Major competitions include the four Grand Slams—Australian Open (hard), French Open (clay), Wimbledon (grass), and the US Open (hard)—alongside numerous international and national events. Tennis is also adapted in para-sport forms such as wheelchair tennis.
