Except water isn't wet. Things touched by water are wet. Common mistake.
Seriously? Is that just language semantics or does it actually make sense to apply this definition of (fluid) water being dry? Also, doesn't water touch itself and is thus wet too?
Wetting is an interaction between liquids and solid surfaces. If water can't wet a given surface/wet it effectively, it's what you'd call water repellent. Like rain gear, flys on tents, etc.
Where does one water begin and another end? Seems to me any appreciable amount of water is touching other water.
