 (P) is often thought to be in tension with the idea that each expression has the meaning it does in virtue of the way it is used within some linguistic community. The conflict is supposed to arise because (i) the use of an expression is exhausted by its employment in speech acts, and (ii) it is sentences, not words, that can be employed to make speech acts. Against this, it can be argued that referring is among the speech acts speakers routinely perform and that this speech act is done with words, not sentences. One might try to replace (i) with a stronger claim, for example, that the use of an expression is exhausted by its employment in asserting, asking, commanding, and a few of other speech acts not including referring. But even if true the stronger claim may not save the argument against (P) because, at least prima facie, we can make assertions uttering isolated words; cf. Stainton (2006). Davis (2003) develops a detailed theory of meaning that combines (P) with a version of the use theory of meaning.
