   Every each, every one. [Obs.] "Every each of them hath some
      vices." --Burton..

   Every now and then, at short intervals; occasionally;

      [1913 Webster]

   Note: Every may, by way of emphasis, precede the article the
         with a superlative adjective; as, every, the least
         variation. --Locke.

   Syn: Every, Each, Any.

   Usage: Any denotes one, or some, taken indifferently from the
          individuals which compose a class. Every differs from
          each in giving less prominence to the selection of the
          individual. Each relates to two or more individuals of
          a class. It refers definitely to every one of them,
          denoting that they are considered separately, one by
          one, all being included; as, each soldier was
          receiving a dollar per day. Every relates to more than
          two and brings into greater prominence the notion that
          not one of all considered is excepted; as, every
          soldier was on service, except the cavalry, that is,
          all the soldiers, etc.
          [1913 Webster]

                In each division there were four pentecosties,

                [soldiers].                       --Jowett
                                                  (Thucyd. ).
          [1913 Webster]

                If society is to be kept together and the

                each for himself with every one else his foe.
                                                  --J. H.
