Biographical → It is formed from "bio-" (from Greek "bios", meaning life) and "graphia" (from Greek "grapho", meaning to write). The word "biographical" refers to something that is written about a person's life.
Think of 'bio-' meaning life and 'graphia' meaning to write — so biographical is about writing someone's life story.
