Pool

Japanese: プール

(1) A type of billiards. A game in which players use one cue ball to drop 15 balls into a pocket. (2) A large, man-made tank for swimming. Swimming pool. The original meaning of the word pool was "puddle." This name was used because puddles formed by meandering rivers had no current and were suitable for splashing around in the water, bathing, and swimming. Eventually, a swimming moat was built around it, and the word came to mean a puddle drawn from the river. Alternatively, a partition and auxiliary facilities were installed in a lake or on the coast where there were few waves, making it a pool. In the 19th century, indoor pools began to be built in cities such as Vienna, and they became popular with many people. These facilities were more focused on bathing and sunbathing. Eventually, heated pools were built, and people could enjoy swimming all year round. In Japan, in the 1960s, the effects of pesticides made it almost impossible to swim in rivers, so efforts were made to build swimming pools in schools and local communities. In the 1970s, when the seawater at beaches began to become polluted by industrial wastewater and other things, large swimming pools began to be built on the coasts to replace the beaches. Large, artificial, flowing water pools and wave pools appeared.

（１）ビリヤードの種目の一つ。１つの手球(てだま)で15個の球をポケットに落とすゲームのこと。（２）水泳を行うために人為的に作られた大きな水槽。スイミング・プール。プールのもともとの意味は〈水たまり〉。川が蛇行(だこう)してできた〈水たまり〉が流れがないので，水遊びや水浴び，水泳に適していたことから，この名が用いられるようになった。やがて，水泳用の堀割とその周りに水泳用の付帯施設を設置し，川から水を引いた〈水たまり〉のことを意味するようになる。あるいは，湖や海岸の波の少ないところに仕切りと付属施設を設けてプールとした。　19世紀に入ると，ウィーンなどの都市には室内プールが設けられるようになり，多くの人で賑わった。これら施設は，どちらかといえば，水浴と日光浴に比重が置かれていた。やがて，温水プールが設けられるようになり，一年をとおして水泳が楽しめるようになった。　日本では，1960年代には農薬の影響で川での遊泳がほとんどできなくなり，学校や地域社会のプール設置に力が注がれた。また，1970年ころから海水浴場の海水が工場排水などで汚染されはじめると，海水浴場に代わる大きなプールが海岸に設置されるようになった。人工の，大掛かりな流水プールや波打ちプールが登場。
