Word Origin & History

iron 
O.E. isærn (with M.E. rhotacism of -s-), from P.Gmc. *isarnan (cf. O.S. isarn, O.N. isarn, M.Du. iser, O.H.G. isarn, Ger. Eisen) "holy metal" or "strong metal" (in contrast to softer bronze) probably an early borrowing of Celt. *isarnon (cf. O.Ir. iarn, Welsh haiarn), from PIE *is-(e)ro- "powerful, holy," from PIE *eis "strong" (cf. Skt. isirah "vigorous, strong," Gk. ieros "strong"). The verb meaning "press clothes" (with a heated flat-iron) is first recorded 1680; ironing board is from 1843.
"Right so as whil that Iren is hoot men sholden smyte." [Chaucer, c.1386]
To have (too) many irons in the fire "to be doing too much at once" is from 1549. Iron lung "artificial respiration tank" is from 1932. Ironside, name given to a man of great hardihood or bravery (1297) first applied to Edmund II, king of England (d.1016), later also to Oliver Cromwell and his troops.
