In fact, although both "thrifty" and "stingy" involve the meaning of saving and controlling expenses, there are obvious differences in the tone and evaluation between the two. 1. Frugality is usually a positive word, describing a reasonable and frugal lifestyle, emphasizing not excessive waste beyond necessary consumption, and reflecting a positive attitude towards life. 2. Stingy is derogatory. In addition to saving money, it also implies unnecessary and excessive stinginess, unwillingness to spend on others or necessary things, and often gives people a stingy and unpleasant impression. Therefore, when translating, words should be selected according to the specific context. If the original text emphasizes a healthy and reasonable saving habit, it is more appropriate to use "thrifty"; only when portraying a negative image, criticizing excessive saving or stinginess, it is more accurate to use "stingy". Directly translating "thrifty" into "stingy" may bring unnecessary negative evaluations, so it needs to be carefully considered.
