   Syn: Indigence; penury; beggary; need; lack; want;
        scantiness; sparingness; meagerness; jejuneness.

   Usage: Poverty, Indigence, Pauperism. Poverty is a
          relative term; what is poverty to a monarch, would be
          competence for a day laborer. Indigence implies
          extreme distress, and almost absolute destitution.
          Pauperism denotes entire dependence upon public
          charity, and, therefore, often a hopeless and degraded
          state.
          [1913 Webster] Powan
