Sino-Korean coda -l and the syllabic structure of Old Sino-Korean

Old/Middle Chinese codas of the entering tone are well preserved in Sino-Korean except for Chinese *-t, which changed to SinoKorean-I. This article claims that Old Chinese coda *-t changed to Sino-Korean-I because coda-t was not fully developed in Old Korean by the time the Sino-Korean phonological system was formed in the eighth century. This article also proposes that the syllabic structure of Old Sino-Korean was (C)V at the earliest stage and gradually changed to (C)V(C). Evidence is presented from place names of the Samguk sagi along with other relevant Old Sino-Korean materials. The results of this study suggest we must reject the views that Sino-Korean coda-I developed under the influence of similar changes that occurred in Chinese dialects, that Middle Chinese coda -t remained the same in Sino-Korean until the sixth century but changed to-I in the seventh century, or that it was realized as -r due to phonetic adjustment caused by released codas of Old Korean.
