Assemblage \As*sem"blage\, n. [Cf. F. assemblage. See
   {Assemble}.]
   1. The act of assembling, or the state of being assembled;
      association.

            In sweet assemblage every blooming grace. --Fenton.

   2. A collection of individuals, or of individuals, or of
      particular things; as, a political assemblage; an
      assemblage of ideas.

   Syn: Company; group; collection; concourse; gathering;
        meeting; convention.

   Usage: {Assemblage}, {Assembly}. An assembly consists only of
          persons; an assemblage may be composed of things as
          well as persons, as, an assemblage of incoherent
          objects. Nor is every assemblage of persons an
          assembly; since the latter term denotes a body who
          have met, and are acting, in concert for some common
          end, such as to hear, to deliberate, to unite in
          music, dancing, etc. An assemblage of skaters on a
          lake, or of horse jockeys at a race course, is not an
          assembly, but might be turned into one by collecting
          into a body with a view to discuss and decide as to
          some object of common interest.
