Iron
Definition:
(n.) 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.
(n.) An instrument or utensil made of iron; -- chiefly in composition; as, a flatiron, a smoothing iron, etc.
(n.) Fetters; chains; handcuffs; manacles.
(n.) Strength; power; firmness; inflexibility; as, to rule with a rod of iron.
(n.) Of, or made of iron; consisting of iron; as, an iron bar, dust.
(n.) Resembling iron in color; as, iron blackness.
(n.) Like iron in hardness, strength, impenetrability, power of endurance, insensibility, etc.;
(n.) Rude; hard; harsh; severe.
(n.) Firm; robust; enduring; as, an iron constitution.
(n.) Inflexible; unrelenting; as, an iron will.
(n.) Not to be broken; holding or binding fast; tenacious.
(v. t.) To smooth with an instrument of iron; especially, to smooth, as cloth, with a heated flatiron; -- sometimes used with out.
