I think you’re too rigid with your definitions. I just showed you an example of where water, usually not countable, is used in a plural form in real world usage.
Regardless of whether the noun is countable, the thing itself (water, air) absolutely is countable, i.e., comes in discrete measurable amounts, which is the more important issue here.
I believe there are about 55.508435 moles of H2O in a liter of water at sea level (basically assuming 1 liter of water = 1kg of water)
A mole is countable. Water is not.
Atoms of water are measured in moles. Atoms are discrete units, a mole is just a certain number of them
So you understand then why water is uncountable but atoms are not. Congratulations. What a strange pedantic hill you choosing to die on.
No, water is countable. Unfortunately you are incorrect.
EDIT: the word “water” isn’t usually made plural, but water the substance can absolutely be measured and counted.
Sorry but some nouns (ie cats) can be counted while others (ie air) cannot be.
Language is a flexible thing. I heard this in a children’s game of tag, “Octopi, Octopi, can I cross your waters?”
And you can count air too, either by volume or amount of molecules.
I think you should just go and read the wikipedia articles on countable and noncountable nouns and stop arguing with a literal inguist.
