Water

Water is wet. Conventionally. Closer inspection may reveal various problems with water being wet; too little water may not merit the label wet, if one catches a bit of spray from a wave, and with too much water generally one is underwater, only becoming wet after emerging like Godzilla from Tokyo Bay. Something about a towel being important. There's a sensory apparatus involved; is a ribcage wet? Or are those rocks wet? They might only appear to be wet because of a special coating and the angle of the sun coming through the clouds. Does the sky wet, or is it doing something else involving the same amounts of water that located and sensed elsewhere would get tagged as wet? The wetness of soapy water could be completely out of mind as one tries to get that water out of the eyes, or completely in mind as each paw is diligently shook after each step.

One idea might be to use "goeswith" instead of "is" so that wetness goeswith water (and the various other necessary conditions). Less identity, more association?
