The word spouting applies to a strong, narrow flow of liquid that comes out very quickly through a narrow tube and is controlled by tipping by hand, battery, electricity, etc.
Spout is the name given to small pipes on the side of containers that you pour liquid through such as teapots, coffee pots, watering cans for gardens and plants, sprays and air guns.
When made in pottery, the spout is always a part added to the main body and when tipped it allows the liquid it carries to flow out smoothly. The flow is controlled by the size of the spout’s mouth and the degree to which it is tipped, the higher the more the liquid comes out. When designed, the mouth of the spout must always be higher than the level of the liquid when the teapot is full and standing.
