In the first part, this paper illustrated that, “Archive”, as a two-syllabled compound word, was a Chinese translation of the word “”（Dangse）in Manchu language. It was the combination of transliteration and free translation, and can be proved by Qing Wen Hui Shu and Wu Ti Qing Wen Jian these two books. It was made clear in the second part that in former development of Ancient Chinese, the morpheme “Dang” had never been a morpheme of documental nouns until the combination of transliteration and free translation in Manchu translation. At the end of this paper, it illustrated that, the morpheme “An” had always been a major morpheme of documental nouns since Qin and Han Dynasties, and its frequency of use had been on the rise since then and reached its peak in Qing Dynasty. As a result, “Dang” and “An” were combined in translation.
