语法变化的“负向终点”：术语、概念与成因
The "negative end" of change in grammar: terminology, concepts and causes
AI总结：
本文系统梳理语法变化“负向终点”的术语、概念与成因，将丧失、衰退和废弃现象置于语言变化框架中，并分析构式使用频率持续下降直至消失或仅存化石化形式的可能原因。
摘要：
与创新和涌现领域相比，变化的“负向终点”这一主题在很大程度上尚未得到充分研究。然而，近来它已开始受到全球语言学者越来越多的关注。本文的主要关注点有三方面，即讨论与语法变化“负向终点”相关的i）术语；ii）概念和iii）成因。文章首先概述了围绕该主题已开展的研究。随后，将被称为“丧失”“衰退”或“废弃”的现象置于语言变化过程之中进行定位，再详细阐述其背后的术语和概念。最后一部分考察了构式在使用频率上随时间呈现（渐进或快速但非常持续的）下降的可能成因，这种下降一直持续到该构式消失，或仅剩残余形式或化石化形式为止。关键词：丧失、废弃、衰退、竞争、更高
英文摘要：
The topic of "negative end" of change is, contrary to the fields of innovation and emergence, largely under-researched. Yet, it has lately started to gain an increasing attention from language scholars worldwide. The main focus of this article is threefold, namely to discuss the i) terminology; ii) concepts and iii) causes associated with the "negative end" of change in grammar. The article starts with an overview of research conducted on the topic. It then moves to situating phenomena referred to as loss, decline or obsolescence among processes of language change, before elaborating on the terminology and concepts behind it. The last part looks at possible causes for constructions to display a (gradual or rapid, but very consistent) decrease in the frequency of use over time, which continues until the construction disappears or there are only residual or fossilised forms left. Keywords: loss, obsolescence, decline, competition, higher
