Denouement

Denouement is an element in the structure of a story, in which all plot lines typically come to a resolution, events are explained, etc. It usually follows the climax. The term is borrowed from the French word dénouement derived which is.
In the terminology of classical drama the final resolution is traditionally called catastrophe.
Various authors suggest different taxonomies of the story structure. In particular, it is common to include the "falling action" between the climax and the denouement. A denouement may be followed by a conclusion and an epilogue, which may give a moral of the story, outline subsequent events, etc. Alternatively, Henry Albert Philips includes the denouement in the "conclusion".
Short stories, with their economy of words, often do not need an elaborate denouement.
Typically a denouement is at the end of the narrative, but it may also start the story, acting as a teaser. Usually a denouement follows the logic of the course of the events, but sometimes it may be unmotivated, what is called "deus ex machina", as in some ancient Greek tragedies of Sophocles or Euripides.
Another common type of a denouement is a happy ending.
