Origin of iron

  • Middle English iren from Old English īren eis- in Indo-European roots

    From American Heritage Dictionary of the English Language, 5th Edition

  • From Middle English iren, a rhotacism of Old English īsern, īsærn, īren, īsen, from Proto-Germanic *īsarną (compare Dutch ijzer, West Frisian izer, German Eisen, Danish jern), from Gaulish īsarno-, from Proto-Celtic *īsarno- (compare Welsh haearn, Irish iarann), from Proto-Indo-European *h₁ésh₂r̥ (“blood”) (compare Hittite (ešḫar), Tocharian A ysār, Latvian asinis, Ancient Greek ἔαρ (ear), Old Armenian արիւն (ariwn), Sanskrit असृज् (asṛj)). The sense development runs from 'blood' to 'blood red' to 'ruddy metal'.
