Lawn tennis については以下を参照(wikiより引用)。

”The modern game of tennis originated in Birmingham,England, in the late 19th century as "lawn tennis".It had close connections both to various field ("lawn") games such as croquet andbowls as well as to the older racquet sport of real tennis. During most of the 19th-century in fact, the term "tennis" referred to real tennis, not lawn tennis.”
