When we define things we first tend to name the item under discussion, then we tend to describe it and then we explain how it is used or functions ... This seems to be a pattern of how to define things properly.
Blue text = Item under discussion
Red text = Narrative
Green text = M.et.a.narrative
The red narrative searches for what is particular about the item itself ... whereas the green text is concerned about how and what patterns all narratives have.
