Wetness is how much moisture is present in the air or on a surface.
When we talk about wetness, it's usually in relation to something being too damp or soggy. You might say, "I don't like walking in the rain because of all the wetness on my shoes," meaning that your shoes are uncomfortable and heavy because they're full of water. Wetness can also be a problem when it comes to clothes, especially if you wear something that's prone to getting damp or soaked through. For instance, "This sweater is really showing its age - it's lost most of its shape due to the constant wetness."
The condition of being wet.
