To furnish or arm with iron; as, to iron a wagon.iron out differences resolve differences; settle a dispute.
To pass an iron over (clothing or some other item made of cloth) in order to remove creases.
Made of the metal iron.
Strong (as of will), inflexible.
the most common and most useful metallic element, being of almost universal occurrence, usually in the form of an oxide (as hematite, magnetite, etc.), or a hydrous oxide (as limonite, turgite, etc.). It is reduced on an enormous scale in three principal forms; viz., cast iron, steel, and wrought iron. Iron usually appears dark brown, from oxidation or impurity, but when pure, or on a fresh surface, is a gray or white metal. It is easily oxidized (rusted) by moisture, and is attacked by many corrosive agents. Symbol Fe (Latin Ferrum). Atomic weight 55.9. Specific gravity, pure iron, 7.86; cast iron, 7.1. In magnetic properties, it is superior to all other substances
an instrument or utensil made of iron; -- chiefly in composition; as, a flatiron, a smoothing iron, etc
fetters; chains; handcuffs; manacles
strength; power; firmness; inflexibility; as, to rule with a rod of iron
of, or made of iron; consisting of iron; as, an iron bar, dust
resembling iron in color; as, iron blackness
like iron in hardness, strength, impenetrability, power of endurance, insensibility, etc.;
rude; hard; harsh; severe
firm; robust; enduring; as, an iron constitution
inflexible; unrelenting; as, an iron will
not to be broken; holding or binding fast; tenacious
to smooth with an instrument of iron; especially, to smooth, as cloth, with a heated flatiron; -- sometimes used with out
to shackle with irons; to fetter or handcuff
to furnish or arm with iron; as, to iron a wagon
Origin: [OE. iren, AS. ren, sen, sern; akin to D. ijzer, OS. sarn, OHG. sarn, san, G. eisen, Icel. sarn, jrn, Sw. & Dan. jern, and perh. to E. ice; cf. Ir. iarann, W. haiarn, Armor. houarn.]
Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal in the first transition series. It is the most common element forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 is the last nuclear fusion reaction that is exothermic. This causes radioactive nickel to become the last element to be produced before collapse of a supernova leads to the explosive events that scatter this precursor radionuclide of iron abundantly into space. Like other group 8 elements, iron exists in a wide range of oxidation states, −2 to +6, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated iron oxides, commonly known as rust. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron metal, and thus iron oxides flake off and expose fresh surfaces for corrosion.
The New Hacker's Dictionary
Hardware, especially older and larger hardware of mainframe class with big metal cabinets housing relatively low-density electronics (but the term is also used of modern supercomputers). Often in the phrase big iron. Oppose silicon. See also dinosaur.
U.S. National Library of Medicine
A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.
