Flash \Flash\, v. i. [imp. & p. p. {Flashed}; p. pr. & vb. n.

   dial. Sw. flasa to blaze, E. flush, flare.]

      of flame and light; as, the lighting flashes vividly; the

            The object is made to flash upon the eye of the

   Syn: {Flash}, {Glitter}, {Gleam}, {Glisten}, {Glister}.

   Usage: Flash differs from glitter and gleam, denoting a flood
          or wide extent of light. The latter words may express
          the issuing of light from a small object, or from a
          pencil of rays. Flash differs from other words, also,
          in denoting suddenness of appearance and
          disappearance. Flashing differs from exploding or
          disploding in not being accompanied with a loud
          report. To glisten, or glister, is to shine with a
          soft and fitful luster, as eyes suffused with tears,
          or flowers wet with dew.

      very brief period.

      and giving a fictious strength to liquors.
