What does rough mean?
Rough describes something with an uneven, coarse, or irregular surface, but the word is far more versatile than that basic physical sense. A rough road may be uneven and hard to travel on, while rough weather involves strong wind, rain, or turbulent seas. A rough estimate is an approximate calculation rather than an exact one, and a rough draft is an early, unfinished version. In descriptions of behavior or circumstances, rough can indicate harshness, difficulty, or lack of refinement: a rough treatment is unkind or careless, and a rough night is an unpleasant one. As a verb, rough can mean to make a surface irregular or to prepare an initial version, though the latter is more common in informal English. As an adverb, rough commonly appears as “roughly,” meaning approximately. Together, these uses make rough useful for describing both physical texture and the uneven or imperfect quality of broader human experiences.
