The term 'floor of a building' can be described by two crossword solutions: STOREY (6 letters) and STORY (5 letters). A STOREY is a level of a building, usually with a floor and ceiling, that is separated from other parts of the building by walls or partitions. A STORY is a narrative or account of events, experiences, or the like, whether true or fictitious. In architecture, a STORY is also used to refer to a level of a building, but it is not as commonly used as the term STOREY.
