Abstract: Some predicates carry special kinds of inferences: subjective predicates carry acquaintance inferences (AIs); evaluative predicates carry practical inferences (PIs). I show that these inferences pattern in parallel ways, which calls for a unified treatment. Moreover, these inferences can hardly be classified under standard categories, such as entailment, presupposition, or implicature. I argue that existent accounts of the AI can hardly be extended to PI; and that the only extant account of both inferences is ad-hoc. In contrast, I aim to derive both inferences from a lexical-expressivist view about the relevant predicates, together with a general constraint on modals, evidentials, and propositional attitude verbs.
