11. Not sure about dirty but more offensive, niggardly. "Niggardly" (noun: "niggard") is an adjective meaning "stingy" or "miserly". It can be traced back at least to the Middle English word nigon, which has the same meaning, and is related to the Old Norse verb nigla, which means "to fuss about small matters".[1]
