用法筆記

Often confused with 'impractical'. 'Impracticable' means something cannot physically or practically be carried out (the plan simply does not work in reality). 'Impractical' means something is not sensible, wise, or efficient (the plan could be done, but it would be a bad idea). Use 'impracticable' when the obstacle is factual impossibility or extreme difficulty.
