Summary and Conclusions

Abstract

This chapter summarizes the central points from each previous chapter and elaborates on the individual analyses of these PSIs (polarity-sensitive items) and their contributions to the critical issues in syntax and linguistic theory. This book studied the microvariation in the syntax of PSIs (negative and positive polarity, negative concord, and negative indefinites) in Standard Arabic and the major regional dialects represented by Jordanian, Egyptian, Moroccan, and Qatari. Overall, the syntactic licensing of PSIs in Arabic bears on key theoretical issues in the cross-linguistic studies of polarity sensitivity. Such issues include the syntactic licensing configurations for these items, the feature of structure/specifications of these items, and the availability of syntactic agreement in the context of negation. Lastly, the chapter presents residual issues for future research.
