Impracticable applies to a course of action that is impossible to carry out or put into practice;impractical, though it can be used in this way, also can be weaker in sense,suggesting that the course of action would yield an insufficient return or would have little practical value.A plan for a new baseball stadium might be rejected asimpracticable if the site was too marshy to permit safe construction; but if the objection was merely that the site was too remote for patrons to attend games easily,the plan would better be described asimpractical. See Usage Note at practicable
Impracticable 用於不可能實行或行不通的動作過程；impractical 雖然也能這樣用， 但也有較弱意思的用法，指動作過程能產生不足的回報或者幾乎沒有實際的價值。如果建築地點過於濕軟而不能保證穩固的建築，那么修建棒球體育場的計畫就可能因其impracticable （不可行）而遭到反對； 但是如果反對的理由僅僅是場址太偏遠而使得愛好者們不能輕易到場觀看比賽的話，這個計畫還是應該被看成是impractical（不切實際的） 參見 practicable
