Prudent 是一个与熟词 student 结尾相同的单词，同时也易与 impudent （粗鲁的）相混淆。该词源自拉丁语providere（前瞻、准备、供应、有远见地行动），14世纪末经古法语prudent（有知识的、审慎的）或者直接由拉丁语prudentem（有知识的、熟练的、睿智的、谨慎的）进入英语后，也是用来表示“谨慎的、审慎的、精明的、深谋远虑的”，常意味着对未来的忧虑或思考，特别是考虑到未来的困难和需求，并通常提前准备好所需的东西，

比如：

It's always prudent to read a contract carefully before signing it.签合同前先好好看一下，这样做永远都是明智的。

The incumbent president of the Republic oscillated between a facile audacity and a prudent realism.该共和国现任总统的施政风格时而轻率鲁莽，时而谨慎务实。

It is imperative that all of us in the Party never forget our original aspiration and founding mission, that we always stay modest, prudent, and hard-working, and that we have the courage and ability to carry on our fight. We must remain confident in our history, exhibit greater historical initiative, and write an even more magnificent chapter for socialism with Chinese characteristics in the new era.权威用例全党同志务必不忘初心、牢记使命，务必谦虚谨慎、艰苦奋斗，务必敢于斗争、善于斗争，坚定历史自信，增强历史主动，谱写新时代中国特色社会主义更加绚丽的华章。
