Form-Narrative structures

A narrative structure is a story's layout and how to write it.Within a story there is always what charicters ?, where is it set?, what conflicts are they? and how does it end.... these are key for a story to work.Also a non-linear narrative is one that does not proceed in a straight-line, step-by-step fashion, such as where an author creates a story's ending before the middle is finished. Linear is the opposite, when narrative runs smoothly in a straight line, when it is not broken up.
