Balls are objects typically used in games. They are usually spherical but can be ovoid. In most games using balls, the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch, marbles and juggling. Balls made from hard-wearing metal are used in engineering applications to provide frictionless bearings, known as ball bearings.

Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see bouncing rubber balls (albeit solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials.

Etymology

The first known use of the word ball in English in the sense of a globular body that is played with was in 1205 in Laȝamon's Brut, or Chronicle of Britain in the phrase, "Summe heo driuen balles wide ȝeond Þa feldes." The word came from the Middle English bal (inflected as ball-e, -es, in turn from Old Norse böllr (pronounced [bɔllr]; compare Old Swedish baller, and Swedish boll) from Proto-Germanic ballu-z, (whence probably Middle High German bal, ball-es, Middle Dutch bal), a cognate with Old High German ballo, pallo, Middle High German balle from Proto-Germanic *ballon (weak masculine), and Old High German ballâ, pallâ, Middle High German balle, Proto-Germanic *ballôn (weak feminine). No Old English representative of any of these is known. (The answering forms in Old English would have been beallu, -a, -e -- compare bealluc, ballock.) If ball- was native in Germanic, it may have been a cognate with the Latin foll-is in sense of a "thing blown up or inflated." In the later Middle English spelling balle the word coincided graphically with the French balle "ball" and "bale", which has hence been erroneously assumed to be its source. French balle (but not boule) is assumed to be of Germanic origin, itself, however.
