  Lightning \Light"ning\ (l[imac]t"n[i^]ng), n. [For lightening,
     fr. lighten to flash.]
     1. A discharge of atmospheric electricity, accompanied by a
        vivid flash of light, commonly from one cloud to another,
        sometimes from a cloud to the earth. The sound produced by
        the electricity in passing rapidly through the atmosphere
        constitutes thunder.
        [1913 Webster]
     2. The act of making bright, or the state of being made
        bright; enlightenment; brightening, as of the mental
        powers. [R.]
        [1913 Webster]
     Ball lightning, a rare form of lightning sometimes seen as
        a globe of fire moving from the clouds to the earth.
     Chain lightning, lightning in angular, zigzag, or forked
     Heat lightning, more or less vivid and extensive flashes of
        electric light, without thunder, seen near the horizon,
        esp. at the close of a hot day.
     Lightning arrester (Telegraphy), a device, at the place
        where a wire enters a building, for preventing injury by
        lightning to an operator or instrument. It consists of a
        short circuit to the ground interrupted by a thin
        nonconductor over which lightning jumps. Called also
        lightning discharger.
     Lightning bug (Zool.), a luminous beetle. See Firefly.
     Lightning conductor, a lightning rod.
     Lightning glance, a quick, penetrating glance of a
        brilliant eye.
     Lightning rod, a metallic rod set up on a building, or on
        the mast of a vessel, and connected with the earth or
        water below, for the purpose of protecting the building or
        vessel from lightning.
     Sheet lightning, a diffused glow of electric light flashing
        out from the clouds, and illumining their outlines. The
        appearance is sometimes due to the reflection of light
        from distant flashes of lightning by the nearer clouds.
        [1913 Webster]

From The Collaborative International Dictionary of English v.0.48 :

  electric current \electric current\, electrical current
  \electrical current\,
     the movement of electrically charged particles, atoms, or
     ions, through solids, liquids, gases, or free space; the term
     is usually used of relatively smooth movements of electric
     charge through conductors, whether constant or variable.
     Sudden movements of charge are usually referred to by other
     terms, such as spark or lightning or discharge. In
     metallic conductors the electric current is usually due to
     movement of electrons through the metal. The current is
     measured as the rate of movement of charge per unit time, and
     is counted in units of amperes. As a formal definition, the
     direction of movement of electric current is considered as
     the same as the direction of movement of positive charge, or
     in a direction opposite to the movement of negative charge.
     Electric current may move constantly in a single direction,
     called direct current (abbreviated DC), or may move
     alternately in one direction and then the opposite direction,
     called alternating current (abbreviated AC).

From WordNet (r) 3.0 (2006) :

      n 1: abrupt electric discharge from cloud to cloud or from cloud
           to earth accompanied by the emission of light
      2: the flash of light that accompanies an electric discharge in
         the atmosphere (or something resembling such a flash); can
         scintillate for a second or more

From Easton's 1897 Bible Dictionary :

     frequently referred to by the sacred writers (Nah. 1:3-6).
     Thunder and lightning are spoken of as tokens of God's wrath (2
     Sam. 22:15; Job 28:26; 37:4; Ps. 135:7; 144:6; Zech. 9:14). They
     represent God's glorious and awful majesty (Rev. 4:5), or some
     judgment of God on the world (20:9).
