The Chinese word **母女 (mǔnǚ)**, meaning "mother and daughter," is a **binomial compound** formed by combining two independent, single-character nouns: **母 (mǔ)**, meaning "mother," and **女 (nǚ)**, meaning "daughter" or "female." This structure follows a common pattern in Chinese where two related terms are juxtaposed to create a new word that denotes a close relationship or a collective pair, with the order typically reflecting social hierarchy or natural sequence—here, the parent precedes the child. The compound efficiently encapsulates the reciprocal familial bond into a single lexical unit.
