The term CAMPOUT STRUCTURE can be solved by the four-letter word TENT. A TENT is a structure made of fabric or other material stretched over poles and secured to the ground, used for camping outdoors. It is typically lightweight and portable, making it ideal for outdoor activities such as camping, hiking, and backpacking. Tents come in a variety of sizes and shapes, from small one-person tents to large family tents that can accommodate up to eight people.
