   poor. See Poor.]
   1. The quality or state of being poor or indigent; want or
      scarcity of means of subsistence; indigence; need.
      "Swathed in numblest poverty." --Keble.
      [1913 Webster]

            The drunkard and the glutton shall come to poverty.
                                                  --Prov. xxiii.
                                                  21.
      [1913 Webster]

   2. Any deficiency of elements or resources that are needed or
      desired, or that constitute richness; as, poverty of soil;
      poverty of the blood; poverty of ideas.
      [1913 Webster]

   Poverty grass (Bot.), a name given to several slender
      grasses (as Aristida dichotoma, and Danthonia spicata)
      which often spring up on old and worn-out fields.
      [1913 Webster]

   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
