 First, what is it to apply an expression? It should be clear that the relevant notion of application is that of predication. For instance, we apply a predicate such as “green” when we use it in an assertion, to predicate a property of an object \(x\). In the case of singular terms, similarly, what is of relevance is referential  use.[11]  The notion of application, hence, is more narrow than that of use, since we use our terms in a wide variety of ways that do not include the expression of judgments, as when we ask a question or make a hypothetical statement (see Millar 2004: 162; Reiland forthcominga).
