The Huá-yí-yì-yǔ is a general name for the various wordbooks between the Chinese language and its neighbouring languages compiled from the beginning of the Ming 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. In this paper the first category of astronomy with 85 entries is treated.
There are many scribal errors in these materials. Apart from the shortcomings of the Chinese characters, this may be the main reason why the Uighur word materials in the wordbooks of this class are not highly regarded.
