   Syn: Vicinity; vicinaty; proximity.

   Usage: {Neighborhood}, {Vicinity}. Neigborhood is
          Anglo-Saxon, and vicinity is Latin. Vicinity does not
          commonly denote so close a connection as neighborhood.
          A neigborhood is a more immediately vicinity. The
          houses immediately adjoining a square are in the
          neighborhood of that square; those which are somewhat
          further removed are also in the vicinity of the
          square.
