Sprinkle, perhaps can be defined as a type of RAIN, but in a much lighter form. It is a form of precipitation that is made up of very small droplets of water, and it usually falls from the sky in a light mist. Sprinkle, perhaps is often used to describe a light RAIN shower, or a light dusting of snow. It is also commonly used to describe the act of sprinkling something, such as sugar or salt, over food.
