A Study on Debonding in the Sentence-Initial Position and the Structure of the Sentential Periphery

本研究涉及粒子在句子起始位置的滞留。它旨在解释这种现象背后的句法和语用条件。它还试图澄清句子外围部分的句法结构。得到了以下结果：处于初始位置的搁浅粒子与句末元素（如句末粒子）共享语篇构建功能。它们的相似之处在于它们出现在短语结构的同一层。在这方面，粒子搁浅表明句子外围形成了句法和语篇之间的接口。

This study deals with particle stranding in the sentence-initial position. It aims at explicating syntactic and pragmatic conditions underlying this phenomenon. It also attempts to clarify the syntactic structure of peripheral parts of a sentence. The following results have been obtained. A stranded particle in the initial position shares discourse-constructing functions with sentence-final elements such as sentence-final particles. Their similarities are rooted in their occurrence in the same layer in phrase structure. Particle stranding, in this respect, indicates that the sentence periphery forms an interface between syntax and discourse.
