Which term is used to describe someone who saves money greedily?

The term that accurately describes someone who saves money greedily is "miser." A miser is characterized by an excessive and often irrational reluctance to spend money, often prioritizing the accumulation of wealth over personal enjoyment or the well-being of others. This behavior is driven by a desire to hoard resources, leading to a lifestyle that is frugal to the point of being stingy. Typically, misers are depicted as individuals who go to great lengths to avoid spending, even when it might benefit themselves or those around them.

The other terms have different meanings that do not align with the concept of greedily saving money. For instance, "spendthrift" describes someone who spends money extravagantly or wastefully, which is the opposite of saving. A "philanthropist" is someone who seeks to promote the welfare of others by generous donations of money or resources, showing a willingness to spend for social good. "Surfeit" refers to an excessive amount of something, not specifically related to frugality or saving. Thus, "miser" is the term that best encapsulates the behavior of hoarding money in a greedy manner.
