Syn. -- Fright; affright; terror; trepidation; apprehension; consternation; dismay; agitation; disquiet; disquietude. -- Alarm, 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 Apprehension. [ 1913 Webster ]
