storey
UK: ˈstɔːri | US: ˈstɔːri
n. a level or floor of a building
n. (archaic) a tier or division in a structure
The word "storey" originates from the Old French estoree (meaning "a building, construction"), derived from Latin historia (story, narrative). Over time, it evolved to refer to the "levels" of a building, likely influenced by the idea of "layers" in a narrative or structure. The spelling "storey" is chiefly British, while "story" (same etymology) is used in American English for both the narrative and architectural senses.
