Iron 铁

在西亚古苏美尔语中，铁被叫做“安巴尔”，意思是“天降之火”（陨石）。古埃及人把铁叫做“天石”。 在古人类发现铁时，由于其坚硬的特性，被命名为 Iron（“铁”），该词源于拉丁语，意为“坚固”、“刚强”的意思。

铁的元素符号“Fe”，源自拉丁文“Ferrum”，意指“铁”，系该词的 缩写。

Iron is probably a Celtic contribution to English, but the borrowing took place in the prehistoric period, before the Germanic dialects separated, and so English shares the word with German (eisen), Dutch (ijzen), Swedish (järn), etc. The prehistoric Celtic form from which these all ultimately came was *īsarnon, which some have linked with Latin aes ‘bronze’ and Sanskrit isira- ‘strong’. The ancient Indo- European peoples had already split up into groups speaking mutually unintelligible tongues by the time iron came into general use, so there was never any common Indo-European term for it.
