The Chinese word **水槽** (*shuǐcáo*, meaning "sink" or "water tank") is a compound noun formed through a straightforward semantic combination. It consists of the character **水** (*shuǐ*), meaning "water," and **槽** (*cáo*), meaning "trough," "groove," or "channel." The construction follows a common modifier-head structure in Chinese, where the first element (**水**) specifies the content or purpose, and the second element (**槽**) defines the object's form or function. Thus, a **水槽** is literally a "water-trough," efficiently describing a man-made receptacle designed to hold or channel water.
