      [1913 Webster]

                                                  --Fairfax.
      [1913 Webster]

   2. To inflict or execute, especially in vengeance or passion;
      to hurl or drive; as, to wreak vengeance on an enemy; to
      wreak havoc.
      [1913 Webster]

   Note: The word wrought is sometimes assumed to be the past
         tense of wreak, as the phrases

   wreak havoc and

   wrought havoc are both commonly used. In fact,

   wrought havoc is not as common as

   wreaked havoc. Whether wrought is considered as the past
      tense of wreak or of work,

   wrought havoc has essentially the same meaning.
      Etymologically, however, wrought is only the past tense of
      work.
