Answer:
The main difference is in length. Short stories generally range anywhere from 1,500 to 30,000 words whereas novels start from about 50,000 words.  
A short story has one main character and the story is told from that character's point of view, mainly first person. A novel has a cast of characters and the story can be told from any of those characters' viewpoints.

Answer:
This question is incomplete. I assume that you need to find the word that fits with that description. The word you are looking for is Theme.
Explanation:
 Literary themes refer to the main idea or the content of the literary work, regardless of gender. That is, the great themes, love, hate, death ... of literary works are treated equally in theater, poetry, narrative, etc.
 It is a concept similar to that of the "artistic theme" in any art other than literature. Therefore, when we speak of literary themes, we refer to the matters dealt with in poems, poetry books, novels, plays, stories, etc.
