Etymology

Origin of iron

First recorded before 900; Middle English, Old English īren (noun and adjective), perhaps from unattested īsren, metathesized from īsern, variant of īsen; compare Old Saxon, Old High German, Old Norse īsarn, Gothic eisarn, from Germanic īsarnam, perhaps from Celtic; compare Gaulish Ysarno-, Iserno- (in placenames), Old Breton hoiarn, Welsh haearn, Old Irish íarn

Explanation

Iron can refer to a common metal. It can also be that thing you use to get wrinkles out of your clothing. If you’re planning to wear linen, you might need an iron to smooth it out. When you use an iron to iron your clothes, you’re also using both the noun and verb form of iron. The noun describes the appliance and the verb describes the action of using it. Iron can also refer to a golf club, like that 5-iron you always use. If you’ve ever been a cattle rancher, you might also be familiar with a branding iron, a tool used to brand skin with a mark of ownership.
