The kanji 消 is a phono-semantic compound (形声文字 - keisei moji). The semantic component (meaning) is 水 (sui, water), and the phonetic component (sound) is 肖 (shou, which initially meant "to resemble"). The original meaning of 消 was related to the act of removing or diminishing something, like water extinguishing a fire. The water radical suggests the use of water in the extinguishing process. The sound component, 肖, contributes the pronunciation "shou." Over time, the meaning expanded to encompass the broader concepts of disappearing, eliminating, and extinguishing anything.
