The Chinese word **儿女 (érnǚ)**, meaning "children" or "sons and daughters," is a straightforward **compound word** formed by joining two independent, concrete nouns: **儿 (ér)**, meaning "son" or "child," and **女 (nǚ)**, meaning "daughter" or "woman." This formation follows the common coordinative (or并列) structure in Chinese lexicology, where two semantically related characters are combined to create a new, broader concept that encompasses both. The resulting term is a **hyponym** that collectively refers to offspring, with the combined meaning of "sons and daughters" naturally extending to signify "children" in general.
