praseodymium的词源

英文词源

praseodymium (n.): rare metallic element, 1885, coined in Modern Latin by discoverer Carl Auer von Welsbach (1858-1929) from Greek prasios "leek-green" (from prason "leek") + didymos "double," the name given to an earth in 1840, so called because it was a "twin" to lanthana. When didymia was further analyzed in the 1880s, it was found to have several components, one of which was characterized by green salts and named accordingly, with the elemental suffix -ium.

来自希腊语prasios,韭菜绿，来自prason,韭菜。didymium, 钕镨混合物，来自希腊语didumos,双胞胎，因该元素常与镧相联系，词源同neodymium.
