—im·prac′ti·ca·bly adverb Synonyms: impossible, impractical, intractable. That which is impossible cannot be done at all; that which is impracticable is theoretically possible, but cannot be done under existing conditions. Impractical, which strictly means not practical, is coming into frequent popular use as the equivalent of impracticable, but the difference should be maintained; an impractical man lacks practical judgment or efficiency; an impracticable man is difficult to deal with (compare OBSTINATE, PERVERSE); an impractical scheme lacks practical fitness, is theoretic or visionary; an impracticable scheme has some inherent difficulties that would insure its failure in action. Antonyms: easy, feasible, possible, practicable.
