"Rough" or "rugged" describes surfaces or terrains that are uneven, coarse, or harsh. This term is often used to characterize natural landscapes, such as mountains or rocky paths, where the ground is not smooth and can be challenging to navigate. It can also refer to materials that are not refined, like rough wood or unpolished stone. In a broader context, "rugged" can describe a person's character or appearance, suggesting strength and resilience. For example, a rugged individual might be someone who enjoys outdoor activities and embraces challenges, often associated with a tough, adventurous lifestyle.
