And the answer is "Court"

It seems hopscotch is played on a court (see previous posting).

For those who are interested, which assuredly is everybody. Hopscotch dates from the time of Rome and in Britain it was (according to Wikipedia) initially used as a training regimen for Roman infantry who ran the course in full armour and field packs, as it was thought this would improve their footwork. In other words is was not a kid's game
And for those interested in the French connection, which again is assuredly everybody. In Thury they call hopscotch "marcelle" (fem)

A French variant of hopscotch is known as Escargot (snail) or "La Marelle Ronde" (round hopscotch). It is played on a spiral course. Players must hop on one foot to the center of the spiral and back out again. A player marks one square with his or her initials, and from then on may place two feet in that square, while all other players must hop over it. The game ends when all squares are marked or no one can reach the center, and the winner is the player who "owns" the most squares

OK next question - what do the French call a hopscotch "court"
