A fictitious STORY is a narrative that is made up or imagined. It is often used in literature, film, and other forms of art. The term 'fictitious STORY' can be broken down into two words: 'INVENTION' and 'STORY'. INVENTION is defined as the act of creating something new, or the process of devising something from existing ideas or materials. A STORY is a narrative, usually involving characters, events, and settings, that is told or written in order to entertain or inform.
