This water example looks much less obvious because it is narrower, that is, if sound is any element of auditory perception, then water is a very specific example of perception by different senses, so there is no generally accepted definition that “water is what looks and behaves like water” so it appears that water is “really” just a chemical molecule. Although there is really no “really” here either, water is just a word, and it can just as well be used for what behaves like water, and not for what what behaves like water is chemically in our the world.
In my opinion, this should generally be added as a second example in the “standard dispute about definitions”, in addition to “the sound of a tree falling in the forest”, so that there is an extremely non-obvious example of this delusion, including in disputes not among philosophers.
