The Huá-yí-yì-yǔ (華夷譯語) is a general name for the various wordbooks between the Chinese language and its neighboring languages compiled from the beginning of the Ming (明) dynasty (1368~1644). It has broadly 4 different classes. In the wordbooks of the third class the words of each foreign language were transliterated only in Chinese characters and the letters of the language in question were not used. To this third class belongs the manuscript in the collection of the library of Seoul National University. Its seventh volume is for the Uighur language. It contains 19 categories. Its thirteenth category is 鳥獸門 niǎo-shòu-mén ‘the category of birds and beasts’ with 53 entries. In this paper, the Mongolian elements of the thirteenth category 鳥獸門 niǎo-shòu-mén will be treated. These elements are either the Mongolian loan words or common words between Uighur and Mongolian.
