   ever.]
   1. Through eternity; through endless ages; eternally.
      [1913 Webster]

   Note: In England, for and ever are usually written and
         printed as two separate words; but, in the United
         States, the general practice is to make but a single
         word of them.

   {Forever and ever}, an emphatic "forever."

   Syn: Constantly; continually; invariably; unchangeably;
        incessantly; always; perpetually; unceasingly;
