"Wet" describes something that is covered in or saturated with water or another liquid. For example, when it rains, the ground becomes wet, and you might need an umbrella to stay dry. Wet surfaces can be slippery, so it's important to be careful when walking on them.
In addition to weather, "wet" can also refer to activities like swimming in a pool or playing in the ocean. After a fun day at the beach, you might come home with wet clothes and sandy feet. Wetness is a common part of many enjoyable experiences, especially during summer!
