Hagiographic → It is formed from "hagio-" (from Greek "hagios", meaning holy or sacred) and "graphic" (from Greek "grapho", meaning to write). The word refers to writing about the lives of holy or sacred figures, particularly saints.
Think of 'holy' ('hagio-') and 'writing' ('graphic') to remember that hagiographic means writing about holy figures.
