| The Yuan Dynasty is one of the important stages in the history of Chinese Phonology. The study of sounds in the Yuan Dynasty has mainly been focusing on the Zhongyuan Yinyun(《ä¸åŽŸéŸ³éŸµã€‹)(1324). However, there is too much difference between the Middle Chinese Phonology, represented by Qieieyun(《切韵》), and the Modern Chinese Phonology, represented by Zhongyuan Yinyun. And there are few materials of the Yuan Dynasty, which can be used to explain the difference. Eryayi yinshi(《尔雅翼·音释》) was written in 1320 by Hong Yanzu. It is a book for phonetic notation and new material for us, because nobody has studied its phonetic system. After careful collation we found 1,985 available items of phonetic notation in all. Fanqie and Zhiyin were used as primary methods for phonetic notation. We studied this material and came to the conclusion about the nature of the phonetic system in Eryayi yinshi: it reflects the mandarin system in the Yuan Dynasty and provides a new material for the Study of Chinese Phonology history and Phonology in the Yuan Dynasty.This paper consists of 7 chapters. The first chapter we mainly introduce EryayiYin and its author, writing, phonetic system, style and available materials and our research method. In the second, third and forth chapters we analyze and study the sound, rhyme and tone systems in EryayiYin. In the fifth chapter we compare this phonetic system with the structure of phonetics system of Qieyun. In the sixth chapter we summarize the nature of the phonetic system in EryayiYin on the basic of our study. The last chapter is the concluding remarks.The conclusion of this paper is as following:1. In Eryayi Yinsh there are 34 initials which have following features: Most of the voiced(浊音) initials are kept but a few of them are glossed together with voiceless initials; initial Fei(éž) and initial Fu(æ•·)are merged; Zero initial is enlarged, a few characters with initial Yi(ç–‘)are mixed with initial Yu(å–»);initial Ni(æ³¥) and Niang(娘)are merged; the initial groups of Zhier Zhuang(知二庄)are merged and so do the initial groups of the Zhisan zhang(çŸ¥ä¸‰ç« ), but the groups of Zhier Zhuang and Zhisan zhang do not merge. Xia(匣)and Yu(å–»)are mixed; various initials are glossed interchangeably.2. There are 68 finals and have following features: finals of divisionâ…¢andâ…£are merged, so do the finals of divisionâ… andâ…¡, the differences between double rhym(eé‡éŸµ)is disappeared, so does the differences between double Qi(eé‡çº½); Jiang(江摄)and Dang(宕摄)are combined, so do the rime groups of Xie(蟹摄)and Zhi(æ¢æ‘„),Zeng(曾摄)and Geng(梗摄); Chezhe rhyme is come out; the differences of enter tone(入声)-p, -t and–k are retained,a few are weakened.3. There are four tones: plain tones(平声), rising tones(上声), departing tones(去声) and enter tones(入声). Each tone has yin(阴)and yang(阳), so it develops into eight tones. |
