Niggardness is a word that has been used in the English language for a long time to describe someone who is stingy or miserly. However, because of its similarity to a racial slur, it can be a controversial term to use. If you need to describe someone's stinginess, there are other synonyms you can use, such as frugality, parsimony, meanness, tightfistedness, and avarice. These words can effectively communicate the same type of behavior as niggardness without causing any offense or controversy. When trying to convey your message, it's always important to be mindful of the words you choose.
