A stairway refers to a series of steps or a path leading upward, typically consisting of several risers and treads connected by landings. It is often used as an architectural feature in buildings to provide access between floors, and can also be found outdoors, such as in the form of exterior staircases or fire escapes. The term "stairway" can also refer more broadly to any route or path that leads upward, even if it does not involve physical steps.
