Aggregate \Ag"gre*gate\, n.
   1. A mass, assemblage, or sum of particulars; as, a house is
      an aggregate of stone, brick, timber, etc.

   Note: In an aggregate the particulars are less intimately
         mixed than in a compound.

   2. (Physics) A mass formed by the union of homogeneous
      particles; -- in distinction from a {compound}, formed by
      the union of heterogeneous particles.

   {In the aggregate}, collectively; together.
