The Chinese word "警铃" (jǐnglíng) is a compound noun formed by combining two characters: "警" (jǐng), which means "to warn," "alert," or "police," and "铃" (líng), which means "bell." This follows the common Chinese morphological pattern where a modifier (警) specifies the purpose or type of the head noun (铃), resulting in the meaning "alarm bell"—a bell specifically used for issuing a warning or alert. The formation is semantically transparent, as the meaning of the whole is directly derived from the sum of its parts.
