It's a unique and personal account of their experiences, memories, thoughts, and feelings.
Here's a breakdown of the word:
* Auto: Means "self" or "one's own"
* Bio: Means "life"
* Graphy: Means "writing"
So, put together, autobiography means "writing about one's own life."
It's important to note that autobiographies can vary greatly in style and content. Some might be highly personal and introspective, while others might focus on specific events or periods of the author's life. They can also be written in a variety of forms, from traditional narratives to more experimental styles.
