The word **富裕 (fùyù)**, meaning "prosperous" or "affluent," is a typical Chinese compound formed by combining two independent, synonymous characters. The first character, **富 (fù)**, primarily denotes wealth and abundance, often conceptually tied to a household having ample stores. The second, **裕 (yù)**, conveys the ideas of sufficiency, abundance, and ease. When paired, they create a **synonym compound (联合式)**, where each character reinforces and nuances the other's meaning of ample material wealth and a comfortable, plentiful life, resulting in a term stronger and more comprehensive than either character alone.
