Something being wet is a material property of something getting in contact with water. There are materials not getting wet when submerged, or splashed with water because they wont soak it up. These require a weting agent to make water adhere to it by breaking its surface tension. Cleaning agents mostly use this to make water actually lift dirt of a surface, and not just form droplets which just run off without making the surface actually wet. Nano coatings which create a lotus effect wont get wet at all. If anything, water is liquid, and not wet. We just use the therm wet in daily life just wrong, thats why this retarded copypasta bait keeps getting replies every time over this usually non debatable topic
