Question

Is water wet? I think it is but people think it isn’t

Answer 1

Water isn't wet. Wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. We or our possessions get wet

Answer 2

If you and those people started out by agreeing on a definition of "wet",
I'll bet you could come together on the description of water too.
