<注釋>Nothing hobbles a President so much as impeachment,and there is an etymologicalas well as procedural reason for this.The wordimpeach can be traced back through Anglo-Norman empecher to Late Latin impedic3re, .to catch, entangle,.from Latinpedica, .fetter for the ankle, snare.. Thus we find that Middle Englishempechen, the ancestor of our word,means such things as .to cause to get stuck fast,. .hinder or impede,. .interfere with,. and .criticize unfavorably..A legal sense ofempechen is first recorded in 384. This sense, which had previously developed in Old French,was .to accuse, bring charges against..A further development of the sense had specific reference to Parliament and its formal accusation of treason or other high crimes,a process that the United States borrowed from the British.Although we have used it rarely at the federal level,impeachment stands as the ultimate snare for those who would take advantage of the public trust.
沒有事能象彈劾那樣會使總統陷入窘境了，這既有詞源的原因，又有程式上的原因。impeach 這個詞能夠通過英國法文中的 empecher 追溯到後期拉丁語中的 impedicare ， 意思為.抓住，牽連.，源自拉丁語中的pedica ，意思是.腳鐐，圈套.。 於是我們發現中古英文中的empechen ， 我們現在這個詞的前身，有著諸如.使牢牢困住.，.妨礙或阻止.，.干涉.和.令人不利地批評.等意思。empechen 在法律方面的意思最早在384年被記錄下來。 這個意思，原先在古法文中有一定發展，意思是.控告，指控。.這個意思的進一步發展到議會和議會對叛國罪或其他重大罪行的指控，這一程式是美國從英國那裡借鑑而來的。儘管我們在聯邦一級上很少使用，但是彈劾對於那些濫用公眾信任的人來說是最終的陷阱
