What is often a key purpose of a fable?

A key purpose of a fable is to relay a life lesson. Fables are short stories that often feature animals with human-like qualities and are designed to convey moral themes or practical lessons. These stories illustrate important truths about human behavior, ethics, or social values, encouraging readers to reflect on their choices and actions. The moral of the fable is typically stated at the end, making it clear and accessible for readers to understand the lesson being taught. This educational aspect is what distinguishes fables from purely entertaining narratives or other forms of storytelling.
