Storey is the word for a level or floor of a building, as in a three-storey house; story is a narrative, like a bedtime tale, or a short-lived social media post. In American English, story covers both meanings and storey is rarely used. Memory hook: storey has the extra e, like the extra floor.
The core difference
Story means a narrative or a social post, while storey (chiefly British) means a floor of a building — though American English uses story for both.
- story — a narrative told for information or entertainment: She told the children a bedtime story about a lost dragon.
- storey — a level or floor of a building: The house has three storeys plus an attic.
How to tell them apart
Both words descend from the Latin historia, meaning account or narrative. One theory is that storey came to mean a building level because medieval buildings sometimes had picture friezes telling a story on each floor — so the two words are doublets sharing one distant root, not unrelated look-alikes.
The mix-up shows up most in property listings and building descriptions: British English keeps them separate, so a listing should read a three-storey house rather than a three-story house. American English does not make this distinction at all and uses story for both a floor and a tale, so the confusion mainly affects writers switching between the two varieties.
