Understanding the difference between a biography and an autobiography might seem small, but it often confuses students, writers, and professionals alike.
Many people search for “biography or autobiography” because they’re not sure which word correctly describes a life story.
Many people confuse biography and autobiography, but the difference is simple:
A biography is written by someone else, while an autobiography is written by the person themselves.
Using the right term makes writing clearer and more accurate. This guide will explain the differences, give examples, cover common mistakes, and show when to use each word correctly.
Biography or Autobiography – Quick Answer
Quick Answer:
- Biography: A life story written by someone else about a person.
- Autobiography: A life story written by the person themselves.
Examples:
- Biography: “Steve Jobs” by Walter Isaacson is a famous biography.
- Autobiography: “Long Walk to Freedom” by Nelson Mandela is an autobiography.
Key Tip: If the author is not the subject, it’s a biography. If the author is the subject, it’s an autobiography.
The Origin of Biography and Autobiography
- Biography comes from Greek: bios (life) + graphein (to write) → literally “writing of life.”
- Autobiography adds auto (self) → literally “writing one’s own life.”
History:
- Biographies date back to ancient times, like Plutarch’s Lives (~1st century AD), written by historians.
- Autobiographies became more common in the 18th century, reflecting personal reflection and storytelling, e.g., The Confessions by Jean-Jacques Rousseau.
Understanding the roots shows why auto is key in autobiography—it emphasizes self-authorship.
British English vs American English Spelling
Both words are spelled the same in British and American English, but usage preferences sometimes differ.
| Word | British English | American English | Example |
| Biography | biography | biography | She wrote a biography of Queen Victoria. |
| Autobiography | autobiography | autobiography | He published his autobiography last year. |
Key Point:
Unlike some words (e.g., “colour” vs “color”), there is no spelling difference for biography or autobiography. The main differences lie in style and phrasing rather than spelling.
Which Spelling Should You Use?
Since the spelling is the same in US and UK English, your focus should be on audience and context:
- United States: Same spelling, widely used in academic and media contexts.
- United Kingdom & Commonwealth: Same spelling, common in schools and literary circles.
- Global/SEO-focused writing: Both are universally recognized, so use based on clarity, not regional spelling.
Professional Advice: Ensure consistency in your writing. Don’t mix “biography” with informal alternatives like “bio” unless the context is casual or social media.
Common Mistakes with Biography or Autobiography
Even though spelling is standard, people make mistakes with meaning and usage.
| Mistake | Correction | Explanation |
| Saying “I read an autobiography about someone else.” | “I read a biography about someone else.” | Autobiography means the author wrote it themselves. |
| Writing “My autobiography about Elon Musk” | “My biography about Elon Musk” | You can’t write an autobiography of someone else. |
| Confusing short bios with full biographies | Use “bio” for brief descriptions, “biography” for full-length works | Social media bios are short, biographies are detailed. |
| Using “autobiography” for a fictional story | Use “memoir” or “fictional autobiography” | Autobiography implies factual life account. |
