深入解读
从拼写上来看， impeccable 是一个容易与小站（微信公众号：田间小站）推送过的 implacable 相混淆的单词，两者可以一并联想记忆。
从词源上来看， impeccable 一词于16世纪30年代经法语 impeccable 或者直接由晚期拉丁语 impeccabilis （不会犯罪的）进入英语，最初也是用来表示“不会犯罪的、不可能做坏事的、无罪的”，不过这一含义现已较少使用。
但从这个概念出发，等到了17世纪10年代后， impeccable 开始发展出现在的主要含义指“无瑕疵的、无错误的、无可挑剔的、完美无缺的”，常意味着行为、表现或外表等符合最高得体标准，完美无缺到找不到任何错误和任何可以指责之处。比如：
- 说一口纯正的英语
speak impeccable English - 无可挑剔的端庄举止
impeccable good manners - 他身穿一套素净的灰西装和一件洁白的衬衣。
He was dressed in a sober grey suit and an impeccable white shirt.
