What does roughest mean?
Roughest is the superlative form of rough and means having the greatest degree of roughness. The word can describe a coarse or uneven surface, difficult terrain, an abrasive texture, a harsh sound, or an unpleasant and coarse manner. It is especially common in comparisons: “This is the roughest road in the county,” or “She was the roughest interviewer I have met.” Because rough has several related meanings, the intended sense usually depends on the noun it modifies. When applied to behavior, rough can suggest harshness, lack of politeness, or informality. As an adverb, roughest is possible but much less frequent than the adjective use. The form is standard in both British and American English.
