iron: [OE] 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.
