The compound word 节省 (jiéshěng), meaning "to save" or "to economize", is formed by combining two characters with closely related meanings to reinforce a single concept. The first character, 节 (jié), carries the core idea of "moderation", "restraint", or "frugality". The second character, 省 (shěng), means "to reduce", "to omit", or "to economize". When paired, they create a coordinated, or synonymous, compound where each element amplifies and specifies the other, resulting in a nuanced term that conveys the deliberate action of saving resources through both restraint and reduction.
