This character combines the water radical 氵 with the phonetic component 侵 (invade). Together they suggest the image of water seeping or invading into something, hence the meanings “soak” and “immerse.” In extended use, it also conveys gradual penetration, whether physical (like water damage) or metaphorical (like influence or ideas).
