Frightful \Fright"ful\, a.
   1. Full of fright; affrighted; frightened. [Obs.]
      [1913 Webster]

            See how the frightful herds run from the wood. --W.
                                                  Browne.
      [1913 Webster]

   2. Full of that which causes fright; exciting alarm;
      impressing terror; shocking; as, a frightful chasm, or
      tempest; a frightful appearance.

   Syn: Terrible; dreadful; alarming; fearful; terrific; awful;
        horrid; horrible; shocking.

   Usage: Frightful, Dreadful, Awful. These words all
          express fear. In frightful, it is a sudden emotion; in
          dreadful, it is deeper and more prolonged; in awful,
          the fear is mingled with the emotion of awe, which
          subdues us before the presence of some invisible
          power. An accident may be frightful; the approach of
          death is dreadful to most men; the convulsions of the
          earthquake are awful.
          [1913 Webster]
