Quiz: Remember the definition of mal de mer?
racket sport that is descended from and almost identical to the medieval tennis game jeu de paume ("game of the palm"). Real tennis has been played since the Middle Ages, but the game has become almost completely obscured by its own descendant, lawn tennis. Although real tennis contributed its name and scoring system to lawn tennis, real tennis is now played at fewer than 30 courts in the world. The court at Hampton Court palace, where Henry VIII played, is still used occasionally.
