This paper looks at sentential negation in Maltese and the syntactic be- haviour of a group of negative sensitive indefinite items in Maltese, for which existing literature offers only a partial (and indeed partially incorrect) charac- terisation. We focus on syntactic aspects of the interplay between sentential negation and negative sensitive items (NSIs), both negative concord items (NCIs) and negative polarity items (NPIs). Our primary aim is to provide a solid description of the somewhat complex facts and some formalisation of the syntactic aspects in LFG, building on previous work on syntactic aspects of negation in this framework
