‘隔墙’ literally means ‘separating wall’ — 隔 (gé) means ‘to separate, to partition’, and 墙 (qiáng) means ‘wall’. Together, it refers to a physical wall that divides two adjacent spaces, such as rooms, apartments, or offices. It emphasizes the function of separation rather than structural details, and is commonly used in architectural, residential, or workplace contexts.

Unlike general terms like 墙 (wall) or 挡板 (partition board), 隔墙 specifically implies an interior, non-load-bearing barrier designed to define space boundaries. It’s frequently found in real estate descriptions, renovation discussions, and everyday conversation about living arrangements — for example, when describing shared housing or office layouts where neighbors are separated only by a thin wall.
