15) what is an "episodic" plot structure?

Episodic plot structure is the form of story where the main plot of it is depicted through many sub- plots, or chapter- wise depictions of the story.

Explanation:

In "episodic" plot structure, the characters are the same, recurring in all scenes, along with the themes and settings. But what is different in this structure is the way the story is represented or told. Every episode will have a complete story, a beginning and an ending, without the need for the readers or viewers to refer back to the previous scenes. Every act s independent, but still is connected with the main plot of the story. Every scene/ episode has its own plot, but also shows the overall theme/ plot of the story in it's own way through all the episodes. The standalone character of the story or chapter is what's characterizes "episodic" plot structures. Examples of such plot structure will include most of the common stories or television series of today's times like "Criminal Minds", "Modern Family", "The Big Bang Theory", The series of "Agatha Christie" stories etc.
