The Chinese word 锁链 (suǒliàn), meaning "chains" or "fetters," is a coordinative compound formed by combining two semantically related characters: 锁 (suǒ), which originally means "lock," and 链 (liàn), which means "chain." In this construction, both elements contribute equally to the overall meaning, creating a new, more specific concept that refers to a connected series of metal links, often used for restraining or securing. This type of word formation, where two nouns with related meanings are joined, is common in Chinese and effectively creates a precise composite term where the combination implies a unified object or concept stronger than either part alone.
