The Chinese word **年幼** is a compound adjective formed by combining two independent characters: **年** (nián), meaning "year" or "age," and **幼** (yòu), meaning "young" or "immature." It follows a common grammatical structure in Chinese where the first element (**年**) modifies and specifies the second (**幼**), literally creating the meaning of "young in years" or "of a young age." This combination results in a term that specifically describes youthfulness in terms of chronological age, contrasting with words that might imply childishness in behavior. It exemplifies how Chinese frequently creates precise concepts through the logical pairing of meaningful semantic components.
