The Chinese word **围墙 (wéiqiáng)** is a compound noun formed by combining two meaningful characters: **围 (wéi)**, which means "to encircle" or "to surround," and **墙 (qiáng)**, which means "wall." Together, they create a logical, descriptive term where the first character defines the primary function or characteristic of the object named by the second. Thus, a 围墙 is specifically a "surrounding wall" or an "enclosure wall," distinguishing it from other types of walls by its purpose of delineating a boundary or enclosing an area.
