Tennis is a sport played by hitting a ball with a racket over a net into the court of the opponent.
It can be played one-on-one in singles competition or two-on-two in doubles competition.
Games similar to tennis have been around for hundreds of years, with the modern rules we know today being developed through the 1800s.
Rackets were used from the 16th century on.
The name tennis comes from the French word “tenez” which can be roughly translated to “hold” or “receive” in English.
The first tennis club was founded in Birmingham, England in 1872.

Metal racket frames were introduced in the late 1960s and slowly took over sales from wooden frames, which had previously been used.
Racket strings can be made from materials such as natural gut, polyester, kevlar and nylon.
Tennis balls are made of rubber covered in felt. They are typically yellow.
