A "pair of stairs" is a common phrase that refers to two sets of steps used to ascend or descend in a building or outdoor space. However, there are several other synonyms that can be used to describe this feature. One option is "staircase," which can evoke a grander image of a winding, multi-level structure. Another possibility is "flight of stairs," which emphasizes the act of climbing or descending a set of steps. "Step pair" or "steps duo" are more unconventional alternatives that offer a fresh take on the traditional terminology. Regardless of the chosen phrasing, a pair of stairs serves as an essential component in many architectural designs.
