Which of the following words is synonymous with thrifty and stingy?

The word "parsimonious" is synonymous with both "thrifty" and "stingy." It describes a person who is extremely reluctant to spend money or use resources, often going to great lengths to save. This term carries a connotation of excessive frugality, suggesting a person may prioritize saving over any form of generosity or spending, which aligns perfectly with the meanings of "thrifty" (being careful with resources) and "stingy" (unwilling to part with money).

In contrast, the other options convey meanings that are quite the opposite of being thrifty or stingy. "Generous" suggests a readiness to give more than is necessary or expected, while "lavish" implies spending or giving in an extravagant manner. "Altruistic" denotes selfless concern for the well-being of others, further distancing itself from the notions of frugality or stinginess.
