soggy
Unpleasantly wet and soft from soaking up too much water.
Soggy describes something unpleasantly wet and soft, usually because it has absorbed too much water. Think of a piece of toast that fell into your cereal: it becomes soggy, losing its crispness and turning into a mushy, droopy mess. Crackers left out in humid air get soggy. A sandwich sitting in your backpack all morning might have soggy bread by lunchtime.
The word captures a particular kind of wetness that ruins texture. Rain-soaked sneakers feel soggy and uncomfortable. Leaves on the ground after days of autumn rain become soggy and squish underfoot. A wet sponge is just wet, but a piece of cardboard left in the rain becomes genuinely soggy: limp, heavy, and starting to fall apart.
Soggy usually suggests something negative. Nobody wants soggy french fries or a soggy sleeping bag on a camping trip. When you bite into a soggy cookie, you miss that satisfying crunch. The word perfectly describes that disappointing moment when something that should be crisp or firm has absorbed so much moisture that it's lost what made it good in the first place.
