中文詞源
platinum 鉑，白金
來自西班牙語platina,鉑，白金，來自plata,銀板，詞源同plate,-ina,小詞后綴。-um,表金屬元素。因這種金屬形如白銀，當西班人18世紀初在中南美洲發現這種金屬時，認為這是一種劣質白銀，因而命名platina,小銀，次等白銀。
英文詞源
- platinum (n.)
- metallic element, 1812, Modern Latin, from Spanish platina "platinum," diminutive of plata "silver," from Old French plate or Old Proven?al 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.
