Actuality Entailments, negation, and free choice inferences

Abstract


In some languages, (certain) root modals license Actuality Entailments (AEs) when they are perfective-marked. We discuss two puzzling properties of these constructions: (i) when AE-licensing modals are negated, the result entails the negation of actuality, and (ii) when AE-licensing modals embed disjunctions, no Free Choice inferences are available. We develop an account of (i) and show that, given an implicature-based view of Free Choice, (ii) follows as a consequence.
