You can talk about a fountain playing, but it is unusual. This usage of the verb 'play' is fairly formal and old-fashioned: as you can see from the answers you've had so far, many English speakers are unfamiliar with it. Here's the entry from the Cambridge dictionary which explains it: to direct or be directed over or onto something: - Firefighters played their hoses onto the base of the fire. - A fountain was playing (= sending out water) in the courtyard outside. https://dictionary.cambridge.org/dictionary/english/play This has the same etymology as the usual meaning of 'play', but it is unconnected in meaning. The modern word 'play' is derived from an Old English term meaning 'brisk movement'. You can see this in the phrase "a smile played across his face" which you used in your last notebook entry. As you can see, the use of 'play' to refer to this kind of movement is actually closer to the origins of the word than the more common meaning is.

There are a couple of things you could say: - The fountain is on. - The fountain is jetting/shooting/gushing/spraying water. - The fountain is going. (In this case, "going" means the fountain is working to move water, not that the fountain is moving!)

Thank you, everyone. :)

Flowing... water flows.
