A "stick" is a slender piece of wood that is typically found on the ground, often from trees or shrubs. Sticks can vary in size, shape, and thickness, and they are commonly used in various activities such as crafting, building, or as tools in outdoor settings. In nature, sticks serve important ecological roles, providing habitats for small animals and insects. They can also be used by humans for recreational purposes, such as in games like fetch with dogs or as part of camping equipment for roasting marshmallows over a fire.
