cataract词源中文解释
15世纪初，“瀑布，闸门，水的猛烈冲击”，源自拉丁语 cataracta “瀑布”，来自希腊语 katarhaktēs “瀑布，断水； 一种升降栅门”，是一个形容词复合词的名词用法，意思是“俯冲，下冲”，源自 kata “向下”（参见 cata-）。第二个元素可以追溯到 arhattein “猛击”（在这种情况下，复合词是 kat-arrhattein），或者追溯到 rhattein “猛冲，破碎”。
它在拉丁语中的另一种意义“升降栅门”可能通过法语传入，并给英语带来了“眼病，以晶状体混浊为特征”的含义（15世纪初），意思是“阻塞”（对视力）。相关： Cataractous。
