Title : The Computation of Scalar Implicatures : Pragmatic ,

I provide an overview of current theories of scalar implicature: the pragmatic (or Gricean), the lexical and the grammatical theory. The empirical focus are global and local, but also intermediate implicatures. I argue that the grammatical theory is conceptually less well motivated than even a combination of the pragmatic and the lexical theory, and that the grammatical theory therefore requires strong empirical support. I then focus on a novel empirical phenomenon – intermediate implicatures – which provides empirical support for the grammatical theory. I conclude that it seems necessary to adopt the grammatical theory.
