Debility \De*bil"i*ty\, n. [L. debilitas, fr. debilis weak,
   prob. fr. de- + habilis able: cf. F. d['e]bilit['e]. See
   {Able}, a.]
   The state of being weak; weakness; feebleness; languor.

         The inconveniences of too strong a perspiration, which
         are debility, faintness, and sometimes sudden death.
                                                  --Arbuthnot.

   Syn: {Debility}, {Infirmity}, {Imbecility}.

   Usage: An infirmity belongs, for the most part, to particular
          members, and is often temporary, as of the eyes, etc.
          Debility is more general, and while it lasts impairs
          the ordinary functions of nature. Imbecility attaches
          to the whole frame, and renders it more or less
          powerless. Debility may be constitutional or may be
          the result or superinduced causes; Imbecility is
          always constitutional; infirmity is accidental, and
          results from sickness or a decay of the frame. These
          words, in their figurative uses, have the same
          distinctions; we speak of infirmity of will, debility
          of body, and an Imbecility which affects the whole
          man; but Imbecility is often used with specific
          reference to feebleness of mind.
