Abstract This paper explores the logic behind the various morpho-phonological subdivisions in the verbal system of Palestinian Arabic. It argues for the importance in the understanding of Palestinian Arabic of the apophonic chain proposed for Classical Arabic in Guerssel and Lowenstamm (1993). In Palestinian, it is first argued, the Measure 1 perfective template includes a hard-wired association of its two vocalic positions; the main differences in vocalization between the Palestinian and Classic varieties follow from this fact. The account is then extended to include three large subclasses of weak verbs. Following the analysis of Classical Arabic in Chekayri and Scheer (1996), it is argued that such verbs involve a null element ø, whose realization is determined by the apophonic chain. The second part of the paper provides an account of the entire inflectional paradigms of each of the verbs discussed, a task that was not fully undertaken in previous work. The mechanism of apophony is shown to be at work in this domain, too. An interesting case is discussed of an apparent shift in inflectional paradigm in some forms of the biradical verb. This shift is again shown to follow from the general mechanisms used in the analysis.

阿拉伯语中的apophonic链和弱动词的形式

摘要本文探讨了巴勒斯坦阿拉伯语言语系统中各种形态语音分类的逻辑。它主张在Guerssel和Lowenstamm（1993）中为古典阿拉伯语提出的停机坪链对理解巴勒斯坦阿拉伯语的重要性。首先是在巴勒斯坦，措施1的完善模板包括两个声音位置的硬连接。巴勒斯坦人和古典人之间在发声方面的主要差异是基于这一事实。然后将该帐户扩展为包括弱动词的三个大子类。继在Chekayri和Scheer（1996）中对古典阿拉伯语进行分析之后，有人认为此类动词包含一个零元素ø，其实现方式由养成链决定。本文的第二部分提供了所讨论的每个动词的全部变形范例的说明，这项任务在以前的工作中并未完全完成。无言的机制也被证明在这一领域起作用。讨论了一个有趣的案例，即以双形式动词的某些形式出现的变形范式的明显变化。再次表明，这种转变遵循了分析中使用的一般机制。
