Abstract
This paper is concerned with the syntax of negative sentences and negative polarity items (NPIs) in English and Japanese and argues for the validity of a feature-checking analysis in the framework of Chomsky (1995). It is demonstrated that the feature-checking analysis based on feature specification on Neg and NPIs can present a unified view of negative sentences and that different distributions of NPIs naturally follow from it. At the same time, it is argued that negative sentences suggest a locality condition supplementary to the Minimal Link Condition in Chomsky (1995), in support of Manzini (1998). This locality condition is incorporated into the analysis as the NEG-Convention.
