 On the other hand, there are questions about ability-ascriptions. Abilities are characteristically ascribed (in English) with sentences involving the modal auxiliaries ‘can’ and ‘is able to.’ Accordingly, the central question here is to give a semantics for sentences involving those expressions. Subsidiary tasks include resolving certain open problems in the semantics of these expressions, such as the ‘actuality entailment’ observed in (Bhatt 1999), and integrating a semantics for agentive modals with a semantics for modal expressions more generally. These are, broadly speaking, questions about the semantics of agentive modality.
