Refinedness, also known as refinement, refers to the quality of being polished, cultivated, or sophisticated. Its antonyms, on the other hand, imply a lack of refinement or a character that is dull and unpolished. Some of the most common antonyms for refinedness are coarseness, roughness, crudeness, and boorishness. Coarseness denotes something that is rough or coarse in texture or character, lacking elegance or refinement. Roughness implies lack of smoothness, delicacy, or finish. Meanwhile, someone who displays crudeness is considered unsophisticated, vulgar, or uncultured. Boorishness is a synonym for crudeness, suggesting rude and insensitive behavior that is unrefined and lacking in social skills.
