Is water wet? and what makes water wet?

Water is not wet because to say that something is wet means that the water on the surface of that something can be removed. Water cannot be removed from water. The defintion of wet is "covered or saturated with water or another liquid." which is something a liquid (in this case water) cannot do. If you dump water on water the molecules come together to make more water. If you dump water on the surface of something like a solid this will not happen and it will get wet. This is like asking if fire is burnt, fire cannot be burned, and it is only used as an adjective to show what happens to a solid if it touches it.
