Real tennis

Real tennis is one of several games sometimes called "the sport of kings" – is the original indoor racquet sport from which the modern game of lawn tennis (usually simply called tennis), is descended. It is also known as court tennis in the United States, formerly royal tennis in England and Australia, now real tennis, and courte-paume in France (a reference to the older, racquetless game of jeu de paume, the ancestor of modern handball and racquet games; many French real tennis courts are at jeu de paume clubs).
The term real was first used by journalists in the middle of the 20th century to distinguish the ancient game from modern lawn tennis (even though that sport is seldom contested on lawns these days outside the few social-club-managed estates such as Wimbledon). Real tennis players often call the game "tennis", while continuing to refer to its more widely played offshoot as "lawn tennis".
