Abstract

In this paper we seek an explanation for the preference to use adversative connectives when reinforcing some implicatures. We begin by examining, and rejecting, an hypothesis according to which the nature of the implicatures can encode their argumentative properties. We then argue that this constraint is not due to the nature of the inferences at hand but rather to distinct argumentative relations between the propositions expressed in the discourse. We provide a solution in an argumentative framework and then extend our observations to cases including an overt restriction rather than implicatures. We conclude by looking at various explanations for the source of the preference we observe.
