This paper puts forward an account of the Extended Projection Principle (EPP) based on Chomsky's (2013, 2015) Labeling Theory. Departing from Chomsky's (2015) proposal, which adopts “feature strength” (Chomsky 1993, 1995), it is suggested that the need for Spec,TP to be occupied by a DP can be attributed to labeling reasons, under the assumption that T is a copy of C (these heads being “bundled” in the lexicon of languages of the English type). Given that copies are inert for computational operations (Chomsky 2000, 2001), it follows that they fail to label (Chomsky 2013), which in turn makes it mandatory for Spec,TP to be filled. This article explores the consequences of this proposal for null‐subject languages, in which C and T are regarded as independent lexical items.

关于标签理论中的EPP：来自浪漫史的证据

本文基于乔姆斯基（2013，2015）的标签理论提出了扩展投影原理（EPP）。与Chomsky（2015）的提议采用“特征强度”（Chomsky 1993，1995）不同，建议将Spec，TP由DP占用的需求可以归因于标记原因，假设T为C的副本（这些头在英语类型的语言词典中被“捆绑”）。鉴于副本对于计算操作是惰性的（Chomsky 2000，2001），因此，它们无法标记（Chomsky 2013），这反过来使得必须填写Spec，TP。本文探讨了该建议对空主题语言的影响，其中C和T被视为独立的词汇项目。
