Dependant \De*pend"ant\, Dependance \De*pend"ance\, n.,
Dependancy \De*pend"an*cy\, n.
   See {Dependent}, {Dependence}, {Dependency}.

   Note: The forms dependant, dependance, dependancy are from
         the French; the forms dependent, etc., are from the
         Latin. Some authorities give preference to the form
         dependant when the word is a noun, thus distinguishing
         it from the adjective, usually written dependent.
