platinum
platinum metallic element, Modern Latin, from Sp. platina "platinum," dim. of plata "silver," from O.Fr. plate or O.Prov. plata "sheet of metal" (see PLATE (Cf. plate)). 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.
