unrefined

In a technical sense, the word describes raw materials in their natural state. It carries a neutral, descriptive tone when applied to substances like sugar or oil, often implying a higher nutritional value or "purity" because it hasn't been chemically altered. When applied to people or behavior, the connotation shifts toward the negative. It suggests a lack of social grace or education. Unlike "primitive," which implies a lack of evolution, "unrefined" suggests that the person has not gone through the process of social polishing or etiquette training. It is softer than "vulgar" or "crude," but it still functions as a critique of someone's class or sophistication level, often used in contexts where there is a contrast between high society and common folk.
