I always informally understood "wet" as something having (excess?) water. In that case, I'd say water is not wet because wetness is the result of adding water to something dry, which doesn't apply to water itself.

For water to be wet you'd need "wetness" to be a property you can substract from it, and yet I don't think "dry water" is a concept that exists.

So I'm going with "no".

I take it you're a sedevacantist and ursine outhouse truther as well?

>Wouldn’t what makes it wet instead be classified as making the body of water larger instead?

No. See: wet paint
