Insofar as linearization is a postsyntactic phenomenon pertaining to phonological forms, it is desirable that it be modeled in a violable‐constraint framework, like other PF‐branch phenomena. This paper presents such a model, with the goal of capturing the Final‐over‐Final Condition, a typological generalization that says that head‐final phrases embed only other head‐final phrases, while head‐initial phrases may embed phrases of either headedness. The specific model proposed here, termed Optimal Linearization, is couched in Optimality Theory and comprises three interacting violable constraints on the mapping of syntactic structure to linear order. One constraint, Antisymmetry, closely mimics the action of Kayne's familiar Linear‐Correspondence Axiom. An opposing constraint HeadFinality penalizes deviations from an idealized head‐final order. Lastly, a domain‐specific constraint HeadFinality‐α enforces head‐final ordering only within one constituent, allowing for disharmonic orders that respect the Final‐over‐Final Condition. Optimal Linearization has several advantages beyond typology, including offering insight into the left positioning of specifiers, which can be seen as the emergence of an unmarked preference for head finality. Linearizing at PF also allows us to model cases where phonological or prosodic properties of words affect their order; this is illustrated with the case of Irish pronoun postposing.

最佳线性化：具有可约束的词序类型

只要线性化是与语音形式有关的后句法现象，就希望像其他PF分支现象一样，在线性约束框架中对线性化进行建模。本文提出了这样一个模型，其目的是捕获“最终-最终条件”，这是一种类型学概括，说头-最后短语仅嵌入其他头-最后短语，而头-初始短语则可能嵌入任一头的短语。此处提出的称为最佳线性化的特定模型已包含在最佳性理论中，并且在句法结构到线性顺序的映射中包括三个相互作用的可侵犯约束。一个约束，即非对称性，紧密地模仿了凯恩熟悉的线性对应公理的作用。对立约束H ead F不真实性会惩罚与理想的头定顺序的偏离。最后，特定领域的约束^ h EAD ˚F inality -α强制实施的头，最终排序仅内的一个组成部分，允许尊重末过最后一个条件不和谐的订单。最佳线性化具有超越类型学的几个优点，包括提供对说明符左位置的洞察力，这可以看作是对头部确定性的无明显偏爱的出现。PF的线性化还使我们能够对单词的语音或韵律特性影响其顺序的情况进行建模。爱尔兰代词假说的情况说明了这一点。
