The word **巡逻车** (xúnluóchē, meaning "patrol car") is formed through a logical compound structure in Chinese, combining the verb-object phrase **巡逻** (xúnluó, "to patrol," where 巡 means "to inspect" and 逻 means "to patrol") with the noun **车** (chē, "vehicle"). This creates a descriptive compound noun where the preceding element **巡逻** specifies the function or purpose of the **车**, effectively meaning "a vehicle used for patrolling." It follows the common Chinese word-formation pattern of modifier (function/action) + head (object), resulting in a clear and semantically transparent term.
