Final answer:
Major Walter Clopton Wingfield created 'sphairistikè,' or the outdoor lawn style of tennis, in 1873 as a social pastime for the upper English class.
Step-by-step explanation:
The game known as sphairistikè, which translates to 'skill at playing at ball' from the Greek, and also referred to as lawn tennis, was created by Major Walter Clopton Wingfield. In 1873, he patented a game that he called sphairistikè, which was the precursor to modern outdoor lawn tennis. Major Wingfield designed it as an outdoor activity that could be played on lawns, and it quickly became popular as a social pastime among the upper English class. His version of the game was played on an hourglass-shaped court and simplified many elements of previous racquet sports to make it accessible to a wider audience.
