Alves（2018a）所提出的關於漢語和越語支（Vietic）聲調起源的相對年代的三階段假說，對早期漢越詞（ESV）層次及其漢語詞源有著相當重要的啟發。本研究在擴增語料的基礎下，旨在重新審視相關假設，特別是中古漢語中一些去聲字反映為越南語平聲字的特例之假設，為該假設提供更多的音韻證據及啟發，包含在越南語中可發現的一個更細緻的漢語借詞分層方式。

The three-stage hypothesis about the relative chronology of tonogenesis in Chinese and Vietic posited in Alves (2018a) has raised significant hypotheses concerning the Early Sino-Vietnamese strata and their Sinitic etyma. On the basis of an extended dataset, this study aims to reexamine the relevant hypothesis, particularly the Vietnamese marked Pingsheng (i.e., ngang/huyền) reflexes for Middle Chinese Qusheng items, and modify it with more phonological evidence and implications, including a finer-grained stratification of Sinitic loans found in Vietnamese.
