The paper defines and analyzes the morphosyntactic properties of first-conjunct agreement, which arises when an adjective or verb agrees with the highest/first conjunct of a coordinate noun phrase. This agreement pattern is derived by means of the syntactic operation Agree and a new postsyntactic mechanism which acts as a filter on Vocabulary Insertion within the framework of Distributed Morphology. The proposed filter is called Vocabulary Item Feature Harmony, and roughly consists of (phi-)feature identity between Vocabulary Items. The biaspectual analysis, and especially feature harmony, is used to understand and account for gradable and variable acceptability of first-conjunct agreement, as well as the distribution of this agreement pattern in relation to another agreement pattern, namely, masculine plural agreement (with the coordinate phrase as a whole). The investigation is focused on Bosnian/Croatian/Serbian first-conjunct agreement, but the findings could be extrapolated to similar cases in other languages.

形容词和动词第一连词一致的形态句法方面*

本文定义并分析了首连词一致的形态句法特性，当形容词或动词与并列名词短语的最高/首连词一致时，就会出现首连词一致。这种协议模式是通过句法操作 Agree 和一种新的后句法机制衍生出来的，该机制在分布式形态学框架内充当词汇插入的过滤器。所提出的过滤器称为词汇项特征和谐，大致由词汇项之间的 (phi-) 特征标识组成。偏差预测分析，尤其是特征和谐，用于理解和解释第一个联合协议的可分级和可变可接受性，以及该协议模式相对于另一个协议模式的分布，即，阳性复数协议（与协调短语作为一个整体）。调查的重点是波斯尼亚语/克罗地亚语/塞尔维亚语第一结合协议，但调查结果可以外推到其他语言的类似案例。
