 A widespread distinction that was put forward in an attempt to overcome the dilemma is that between a norm and a normative  proposition.[78]  Consider a normative sentence such as “You may park here for one hour”. This sentence may be used by an authority to provide permission on the spot or it may be used by a passerby to report on an already existing norm (e.g., a standing municipal regulation). The activity of using a normative sentence as in the first case is sometimes referred to as “norming”—it creates a norm by granting permission by the very use of the sentence. The second use is often said to be descriptive, since the sentence is then not used to grant permission, but to report that permission to do so is a standing state. It is often maintained that the two uses are mutually exclusive, and only the latter use allows for truth or falsity. Some have however challenged the exclusiveness of the division, by blending semantics and speech-act theory (especially regarding performatives). They thereby suggest that one who is in authority to grant a permission can not only grant it by performing the speech act of uttering the relevant sentence (as in the first example), but also thereby makes what it said true— that the person is permitted to park (as in the second example with the  passerby)).[79]
