n.mid-13c., from Old French metal “metal; material, substance, stuff” (12c.), from Latin metallum “metal; mine, quarry, mineral, what is got by mining,” from Greek metallon “metal, ore” (senses only in post-classical texts; originally “mine, quarry, pit”), probably from metalleuein “to mine, to quarry,” of unknown origin, but related somehow to metallan “to seek after.” Cf. Greek metalleutes “a miner,” metalleia “a searching for metals, mining.” adj.late 14c., from metal (n.). n.

  1. Any of a category of electropositive elements that usually reflect light, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires. Typical metals form salts with nonmetals, basic oxides with oxygen, and alloys with one another.
  2. An alloy of two or more metallic elements.
  3. An object made of metal.

  1. Any of a large group of chemical elements, including iron, gold, copper, lead, and magnesium, that readily become cations and form ionic bonds, having relatively free valence electrons (electrons in the outer shells). Metals are generally good conductors of electricity because of the freedom of their valence electrons. Metals generally conduct heat well, and in solid form are relatively malleable and ductile compared to other solids. They are usually shiny and opaque. All metals except mercury are solid at room temperature.
  2. An alloy, such as steel or bronze, made of two or more metals.
  3. In astronomy, any atom except hydrogen and helium.
  4. Small stones or gravel, mixed with tar to form tarmac for the surfacing of roads.
