The kanji 消 is a phono-semantic compound (形声文字, keisei moji). The phonetic component is 肖 (shou), which suggests a similar sound. The semantic component, or the meaning component, is often considered to be related to the radical 水 (mizu - water), especially in its early forms. The original meaning was likely related to the fading or disappearing of something, like water evaporating or being washed away. Over time, it broadened to include the act of extinguishing or eliminating things.
