Definition of Tragic Flaw. In literature, the tragic flaw is a character trait that brings about the downfall of the protagonist; ironically, in some works, this flaw is the character's greatest strength taken to an extreme. The tragic flaw may be a lack of judgment or self-knowledge, but most often it is pride or hubris. Regardless of intention, worthiness, station in life, or the character's best efforts, the tragic flaw will bring about the destruction of the character.
A tragedy is a play that ends badly for the hero or heroine or others. A tragedy is usually about a person who has many good qualities, but has one poor quality (called a tragic flaw) that causes trouble for him, and may cause him, or his family or friends, to be in trouble.
