Make a clean breast of it 和 come clean 意思是「和盤托出;全盤招供」,兩者為同義成語,但起源於不同的時代。To make a clean breast of it 中的 breast 並非「乳房;胸部」,而是「心情,思想;心中,心頭」,如 Mary had a troubled breast. (瑪麗心煩意亂);A feeling of envy surged in her breast. (她心中湧起一陣嫉妒)。這個慣用語似乎起源於蘇格蘭,已知它首次出現在印刷品,是在 1752 年被用在《蘇格蘭人雜誌》(The Scots Magazine) 中。
To come clean 則是起源於美國,時間大約是在 1900 年代初期,可能是 make a clean breast of it 的簡寫。必須注意的是,come clean 中的 clean 為副詞,意為「完全地,徹底地」(completely)。它的句型為 to come clean (with sb.) (about sth.),意思是「(向某人) 和盤托出 (某事)」。
例句:
- Amy finally made a clean breast of it and admitted that she was a fan of one-night stands. (艾美終於坦白了,承認她熱衷於一夜情)
- John made a clean breast of all his crimes to the police. (約翰向警方全盤招供他的一切罪刑)
- You ought to make clean with me about the whole matter. (你最好把整個事件一五一十地告訴我)
