Coarse, or rough, describes a texture that is uneven and not smooth. Surfaces that are coarse can feel gritty or bumpy, such as sandpaper or rough stone. This texture can be found in various materials, including fabrics, wood, and natural elements like tree bark. In everyday life, coarse textures can serve specific purposes. For example, coarse salt is used in cooking for its strong flavor and crunchy texture. Similarly, coarse grains in food can provide a hearty feel, while coarse fabrics like burlap are often used for bags and outdoor items due to their durability.
