   Syn: Proposal; offer; statement; declaration.

   Usage: {Proposition}, {Proposal}. These words are both from
          the Latin verb proponere, to set forth, and as here
          compared they mark different forms or stages of a
          negotiation. A proposition is something presented for
          discussion or consideration; as, propositions of
          peace. A proposal is some definite thing offered by
          one party to be accepted or rejected by the other. If
          the proposition is favorably received, it is usually
          followed by proposals which complete the arrangement.
