This study investigates the grammatical status of the so-called Dative particle – eykey and its implications on the syntax of Korean morphological/lexical passives. We first argue that this type of passive derives from causative/experiential constructions in this language. The former and the latter involve the same form of verb, but in the process of passivization the null passive morphology on the embedded transitive verb phrase selected by the matrix causative/experiential morpheme demotes the Dative – eykey -marked Causee in embedded [Spec, VoiceP] position from an argument to an adjunct, besides the embedded transitive lexical verb losing the ability to assign Accusative Case. The so-called animacy restriction on the Nom-marked subject a noun phrase (NP) in – eykey passives is ascribed to the requirement that it takes the Causer/Experiencer role in – eykey passives. In contrast, – ey uyhay passives are derived from the null passive morphology attached to the matrix causative verb complex, thus the matrix Causer/Experiencer subject being demoted and realized with the particle – ey uyhay .

–eykey的语法地位及其对韩国形态被动语的句法含义

这项研究调查了所谓的“格语”“ eykey”的语法状态及其对朝鲜语形态/词汇被动句法的影响。我们首先认为，这种被动是源于这种语言的因果/经验构造。前者和后者涉及相同形式的动词，但是在钝化过程中，矩阵因果/经验语素所选择的嵌入式及物动词短语上的空被动形态将嵌入式[Spec，VoiceP从参数到副词的位置，除了嵌入的及物词动词失去指定宾格的能力外。所谓的“ Noy标记限制”是指– eykey被动对象中具有名词短语（NP）的Nom标记的主体，因为它要求在– eykey被动对象中扮演Causeer / Experiencer角色。相反，– ey uyhay被动语源于附加在矩阵使动词复合体上的空被动形态，因此矩阵– Causey / Experiencer主语被– ey uyhay降级并实现。
