Ripples are little waves on the surface of water caused by the wind or by something moving in or on the water.

When the surface of an area of water ripples or when something ripples it, a number of little waves appear on it.

When the wind ripples plants or trees or when they ripple, they move in a wave-like motion.

If something such as a feeling ripples over someone's body, it moves across it or through it.

If an event causes ripples, its effects gradually spread, causing several other events to happen one after the other.
