Semantic and pragmatic effectsof negative markers
This chapter focuses on the semantic and pragmatic effects associated with the various positions of negation. Particularly, presuppositional readings for negative statements follow from different structural positions of negation (higher in the TP) as opposed to the non-presuppositional interpretations associated with the lower NegP below TP. This chapter also analyses contrasts between SA maa on the one hand and laa and its variants on the other hand. These contrasts are related to scope readings, presupposition, mood and speech acts (commissive, directive, volitive, and (ir)realis). I argue that presuppositional negation is a product of the interplay between syntax and pragmatics. Specifically, I propose that presuppositional negative markers are higher in the syntactic structure. They occupy a position above the tense phrase in the clausal structure, namely NegP above TP (cf. Zanuttini 1997 for similar effects in various Romance). Pragmatically marked negation includes presuppositional negation, categorical negation and cleft-negation. The former two are in a NegP above TP, while the latter is in CP.
