The GIST OF A STORY is the main idea or THEME of a narrative. It is usually the most important part of a story and can be expressed in a single sentence. The term GIST OF A STORY can be broken down into two words: THEME (5 letters) and NUB (3 letters). THEME refers to the underlying message or moral of a story, while NUB is an old English word meaning the essential point or core of something. Together, these two words form the GIST OF A STORY, which is the main point or purpose of a narrative.
