Translation of the Arabic حديد (ḥadīd, “iron”).
From Ossetian Ирон (Iron), a derivation (with the adjective suffix Ossetian -он (-on) from the historical genitive plural Proto-Indo-Iranian *-ānaHam) of Ossetian Ир (Ir). Ossetian Ир (Ir) probably reflexes Proto-Indo-Iranian *wiHrás. Because the Digoron ethnonym for the Ir is Ossetian Ирӕ (Iræ), Cheung (2002) has suggested a derivation from the plural Proto-Indo-Iranian *wiHrā́s. Ossetian Ирон (Iron) is unrelated to Iran despite the superficial similarity in form. Borrowed into the Vainakh languages (and some Dagestani languages) as their exonym for the Ossetes, cf. Chechen Хӏири (Hiri), Ingush Хӏире (Hire).

Iron (US /ˈaɪ.ərn/ or US /ˈaɪrn/; UK /ˈaɪən/) is a chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element in the whole planet Earth, forming much of Earth's outer and inner core, and it is the fourth most common element in the Earth's crust. It is produced in abundance as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to iron) is the last nuclear fusion reaction that is exothermic, becoming the last element to be produced before collapse of a supernova leads to events that scatter the precursor radionuclides of iron into space.
