What “tennisball” means

Wikipedia

A tennis ball is a small, hollow ball used in games of tennis and real tennis. Tennis balls are fluorescent yellow in professional competitions, but in recreational play other colors are also used. Tennis balls are covered in a fibrous felt, which modifies their aerodynamic properties, and each has a white curvilinear oval covering it.
