English
Adjective
unpracticable (comparative more unpracticable, superlative most unpracticable)
-  Not practicable.
-  1869, Alexander Bain, Moral Science; A Compendium of Ethics:- But so unpracticable is this design, that although sometimes conceived, it is never executed; the civil magistrate knows that it would be utterly destructive of human society; sublime as may be the ideal justice that it supposes, he sets it aside on the calculation of its bad consequences.
