   1. The quality or state of being vacant; emptiness; hence,
      freedom from employment; intermission; leisure; idleness;
      listlessness.

            All dispositions to idleness or vacancy, even before
            they are habits, are dangerous.       --Sir H.
                                                  Wotton.

   2. That which is vacant. Specifically:
      (a) Empty space; vacuity; vacuum.

                How is't with you, That you do bend your eye on
                vacancy?                          --Shak.
      (b) An open or unoccupied space between bodies or things;
          an interruption of continuity; chasm; gap; as, a

          or thoughts.
      (c) Unemployed time; interval of leisure; time of

                Time lost partly in too oft idle vacancies given
                both to schools and universities. --Milton.

                No interim, not a minute's vacancy. --Shak.

                Those little vacancies from toil are sweet.
