Fright, Terror, Consternation. These words express
different degrees of fear at the approach of danger. Fright is fear
suddenly excited, producing confusion of the senses, and hence it is
unreflecting. Alarm is the hurried agitation of feeling which
springs from a sense of immediate and extreme exposure. Terror is
agitating and excessive fear, which usually benumbs the faculties.
Consternation is overwhelming fear, and carries a notion of
powerlessness and amazement. Alarm agitates the feelings;
terror disorders the understanding and affects the will;
fright seizes on and confuses the sense; consternation takes
possession of the soul, and subdues its faculties. See
