disappear
💨 消 = dissolve/extinguish + 失 = lose; together: dissolve-and-lose = vanish
消 carries the sense of melting away or extinguishing (water radical 氵 + 肖), and 失 means to lose. The compound names the act of something dissolving out of existence — disappearing, vanishing.
消 — water 氵 + 肖 (phonetic)
消 is a semantic-phonetic compound: the water radical 氵 indicates the meaning, while 肖 (xiào) supplies the sound. It originally described water dwindling or melting away, and from there extended to the modern senses of vanishing, dissolving, and dispelling.
