   Syn: Daily, Diurnal.

   Usage: Daily is Anglo-Saxon, and diurnal is Latin. The former
          is used in reference to the ordinary concerns of life;
          as, daily wants, daily cares, daily employments. The
          latter is appropriated chiefly by astronomers to what
          belongs to the astronomical day; as, the diurnal
          revolution of the earth.
