When do we use the singular plural form of word?
Fish. Water. Information. Electricity. Mist. Air. Everything.
I think we use this form when we think of word as fluid, as opposed to solid or discrete entity. It makes no sense to talk of an individual water, because as a fluid, water can be divided indefinitely. It makes no sense to track an individual water, as one water gets replaced by another water continuously. As they say, you can’t step in the same river twice.
What is it like to see everything in a continuous state of becoming? We’d see only fluid.
As a language exercise, drop all plural form of word. See the thing around us as fluid.
