Narreme is the basic unit of narrative structure. According to Helmut Bonheim (2000), the concept of narreme was developed three decades earlier by Eugene Dorfman and expanded by Henri Wittmann, the narreme is to narratology what the sememe is to semantics, the morpheme is to morphology and the phoneme to phonology. The narreme, however, has yet to be persuasively defined in practice. In interpretative narratology constrained in a framework of principles and parameters, narration is the projection of a narreme N⁰, the abstract head of a narrative macrostructure where Nⁿ dominates immediately N^n-1 (Wittmann 1995).^{[incomprehensible]}
