When we look at the differences between a novel and a novella, a few important points stand out:

1. Length:

   • A novel usually has between 40,000 and 100,000 words or even more.
   • A novella, however, is shorter. It typically has between 20,000 and 40,000 words.

2. Complexity:

   • Novels often include many storylines and a lot of characters.
   • Novellas usually focus on one main story and have fewer characters. This makes the story easier to follow.

3. Theme and Focus:

   • Novels can explore deep themes and show how characters grow over time.
   • Novellas concentrate on a particular theme, allowing for a strong but shorter look at ideas.

For example, George Orwell's "Animal Farm" is a novella that shares important ideas about power and corruption in a short way. On the other hand, a novel like "War and Peace" brings together many characters and historical events in a long and complex story.
