On the left, 氵 is the water radical, showing flowing water and the movement of the sea. The right side adds the sound ロウ and suggests motion that does not stay put, swelling and fading again and again. Together, 浪 captures the image of waves that rise, crash, and drift away. From the restless movement of water came meanings like wandering, drifting through life, and even wasting time or money.
