Even though novels and short stories are different kinds of writing, they do share some things. The biggest difference between them is that novels are long stories written in regular language, while short stories are brief stories written in regular language. Novels have a big story with a main person who the story is mostly about. In the same way, short stories have a story with a main person too.
Novels have lots of events that are all connected to the main situation. Short stories also have many events connected to the main situation. Both novels and short stories are meant to be fun for people to read. In novels, the characters, actions, and events all fit together and feel connected, making the story feel whole. Short stories have this feeling of everything fitting together too. The reason for this close connection is the close relationship between characters, events, and actions.
So, you can see that novels and short stories have some things in common.
