While not every narrative includes all these elements, the purpose of this subdivision is to show that narratives have inherent structural order. Labov argues that narrative units must retell events in the order they were experienced because narrative is "temporally sequenced". In other words, events do not occur at random but are connected to one another; thus "the original semantic interpretation" depends on their original order. To demonstrate this sequence, he breaks a story down into its basic parts. He defines "narrative clause" as the "basic unit of narrative" around which everything else is built. Clauses can be distinguished from one another by "temporal junctures", which indicate a shift in time and separate narrative clauses. Temporal junctures mark temporal sequencing because clauses cannot be rearranged without disrupting their meaning.
