可别度对受事次话题句的影响——以吴语台州话为例

On the effect of identifiability upon sentences with a patient subtopic:A case study of the Taizhou Wu dialect

吴语台州话中的受事次话题句与语言单位的可别度有关:在其他条件相同的情况下,受事论元的可别度越高,在语序编码上也越倾向前置于动词充当次话题。影响受事论元可别度的因素主要有受事论元的指称性、信息度和动词的完成性等。这三个因素对可别度的影响程度也是不同的,它们之间构成了一个优先等级序列,即:完成性>信息度>指称性。

In the Taizhou Wu dialect,the identifiability of patient arguments affects the ordering and grammaticality of the sentences with subtopics denoting patients.Specifically,the more identifiable the patient,the more is it prior to the verb and functions as the subtopic rather than an object in the post-verbal position.The identifiability of patient,in its turn,is influenced by various factors including referentiality,information status and verb-related perfectivity,which are not equally significant but constitute a hierarchy of 'perfectivity > information status > referentiality'.
