"Natatorium" Natural Recordings by Native Speakers
A natatorium is a building or structure that houses a swimming pool, typically a public or community pool for recreational or competitive swimming purposes. The term can also refer to a swimming pool itself, especially a large or luxurious one.
Natant refers to being suspended or floating in the water, typically with the back flat and the body afloat. It is often used to describe the position of aquatic animals such as fish, but can also be used figuratively to describe someone or something that is "floating" or "struggling" to stay afloat in a difficult situation.
