prob. fr. de- + habilis able: cf. F. d['e]bilit['e]. See

                                               --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.
