The opposition between Chongniu in Korean Hanja:Characteristics of standard pronunciations in Middle Chinese from the perspective of initial-medial pattern in Korean Hanja
The dentals and laryngeals in Korean Hanja does not reflect the opposition between Chongniu(重纽,redundant syllables in the rhyme table)A and Chongniu B in early Middle Chinese represented by Qieyun.Instead,they present the opposition between Chongniu B plus third division and Chongniu A plus fourth division in late Middle Chinese.The initial-medial pattern of Korean Hanja indicates that,labiodentals appeared while medials were dropped,and the jing(精)group was pronounced as the fourth division.Besides,separation between the zhuang(庄)group together with second division of zhi(知)group and the zhang(章)group together with thrid division of zhi group also began to occur.This conforms with the system described in Huilin's Yiqiejing yinyi(一切经音义),Shao Yong's Sheng yin changhetu(声音倡和图)and Mongolian Word Rhyme(蒙古字韵),implying the stability of ancient standard pronunciation.Variations which cannot be explained by historical phonological chains suggest that the pronunciation of standard Chinese was flexible in different systems.Some similarities shared in marginal categories cannot be considered as"conservative"and may have a foundation in spoken language.
