The ratio between the number of times something is told and the number of times it can be assumed to have occurred in the storyworld. In singulative narration, there is a one-to-one match between how many times an event occurred and how many times it is told; in iterative narration, something that happened more than once is told once; and in repetitive narration, the number of times something is told exceeds the frequency with which it occurred in the storyworld.
