What's the difference between metallic and opaque?

Metallic


Definition:

  • (a.) Of or pertaining to a metal; of the nature of metal; resembling metal; as, a metallic appearance; a metallic alloy.
  • (a.) Of, pertaining to, or characterized by, the essential and implied properties of a metal, as contrasted with a nonmetal or metalloid; basic; antacid; positive.

  • (20) We support the view that catalysis by metalloenzymes may be a reflection of the chemistry of the metal ion itself as a Lewis acid, and that perhaps too much emphasis has been placed on supposed special characteristics (such as strains, "entasis") of the enzyme-metal ion association.

Opaque


Definition:

  • (a.) Impervious to the rays of light; not transparent; as, an opaque substance.
  • (a.) Obscure; not clear; unintelligible.
  • (n.) That which is opaque; opacity.

Example Sentences:

  • (1) "Maybe dullness is associated with psychic pain," Wallace wrote at one point, "because something that's dull or opaque fails to provide enough stimulation to distract people from some other, deeper type of pain that is always there, if only in an ambient low-level way, and which most of us spend nearly all our time and energy trying to distract ourselves from."
