The apophonic chain and the form of weak and strong verbs in Palestinian Arabic

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.
