4 Comparison and Discussion

    <Paragraph position="0"> While the TAG analysis imposes certain limitations on the ordering of morphemes, it does provide a very simple and intuitive way to describe restructuring verbs as a natural class that includes auxiliary verbs, the other kinds of verb stems which are &amp;quot;transparent&amp;quot; to negative concord. In contrast, The CCG analysis has a technical flavor, and it is not clear to what extent it reflects a linguistic intuition. The CCG analysis does, however, capture the distribution of the negation morphemes in PA. It would therefore be interesting to explore further whether the Hepple-style feature/modality approach could be associated with some linguistic phenomenon.</Paragraph>
    <Paragraph position="1"> One interesting possibility would be to use Steedman's theory of intonation (Steedman, 2000a) to explore the prosodic properties of restructuring sentences in Arabic (and in other languages) to see whether the availability of restructuring correlates with certain prosodic properties. There has been very little study of sentential intonation in Arabic, and so very little empirical basis for an investigation. However, should such an investigation bear fruit, it might suggest that Hepple's approach to extraction constraints could be recast as a theory of intonation. This would allow powerful generalizations to be stated relating the prosodic properties of sentences in PA and other languages to their syntactic properties.</Paragraph>
