Etymology

The word "stairwell" combines "stair," derived from Old English stǣger (meaning "steps for climbing"), and "well," from Old English wella (originally "a spring or stream," later extended to mean "an enclosed space"). The term emerged in the 19th century to describe the architectural feature of a staircase enclosed within a vertical shaft, reflecting the functional merging of the two concepts.
