中英词源

platinum 铂，白金

来自西班牙语platina,铂，白金，来自plata,银板，词源同plate,-ina,小词后缀。-um,表金属元素。因这种金属形如白银，当西班人18世纪初在中南美洲发现这种金属时，认为这是一种劣质白银，因而命名platina,小银，次等白银。

platinum (n.): metallic element, 1812, Modern Latin, from Spanish platina "platinum," diminutive of plata "silver," from Old French plate or Old Provençal plata "sheet of metal" (see plate (n.)). The metal looks like silver, and the Spaniards at first thought it an inferior sort of silver, hence the name platina. It was first obtained from Spanish colonies in Mexico and Colombia, brought to Europe in 1735, and identified as an element 1741. Taken into English as platina (c. 1750), it took its modern form (with element ending -ium) in 1812, at the time the names of elements were being regularized. As a shade of blond hair, attested from 1931. As a designation for a recording that has sold at least one million copies, it is attested from 1971.
