The Reconstruction of the Coda of Zeng(曾)and Geng(梗)Rhyme Groups and the Syllable Structure of Middle Chinese
Some scholars have proposed that the nasal coda of the Middle Chinese Zeng(曾)and Geng(梗)rhyme groups is-(η).From the perspective of the Middle Chinese sound system,the-(η)coda is not an independent phoneme.By establishing strict principles of phonological comparison,it can be found that the Middle Chinese data of transcription does not reflect the-(η)coda.The Korean Hanzi pronunciation reflects the contrast of redundant syllables in the late Middle Chinese period,while the Japanese transcription of Chinese reflects the vowel harmony mechanism in Japanese itself.The Vietnamese Hanzi pronunciation reflects that only the main vowel of the Geng(梗)rhyme group in Middle Chinese has the[+front]feature.The Tibetan-Hanzi transcription reflect the evolution process of the loss of the dang and Geng(梗)rhyme codas in the Northwestern dialect of Middle Chinese.The Korean Hanzi pronunciation,Tibetan-Hanzi cophonological pairs,and contemporary dialects all reflect that Mandarin Chinese allows the VniCo syllable structure,but this type of syllable distribution is limited and not common.The evolutionary regularities of these syllables are worth further exploring in conjunction with the evolution of entering tone rhymes in contemporary times.
