The Chinese word **未婚 (wèihūn)**, meaning "unmarried," is a concise compound formed through straightforward semantic combination. It consists of the negation prefix **未 (wèi)**, meaning "not yet" or "has not," directly modifying the core character **婚 (hūn)**, which means "marriage" or "to marry." Therefore, the term is constructed logically as "not-yet-married," functioning as a stative verb or adjective to describe marital status. This follows a common and productive grammatical pattern in Mandarin where **未** is used to negate actions or states that have not occurred, similar to other words like 未知 (wèizhī, "unknown").
