The kanji 潜潜 is a phono-semantic compound (形声文字, keisei moji). It combines the water radical 氵 (san-sui) on the left side, indicating a connection to water, and the phonetic component 㚘 (shin) on the right side, which suggests the sound and possibly the meaning of "to penetrate" or "to hide." This formation clearly illustrates the concept of submerging or hiding within the water or under the surface, tying the visual to the act of concealing oneself.
