The word **隶属** (lìshǔ) is a compound formed by combining two characters with related meanings to express a specific concept of subordination. The first character, **隶** (lì), carries the core meaning of "to be attached to" or "to be under the authority of," historically referring to a subordinate or servant. The second character, **属** (shǔ), means "to belong to," "to be under," or "category." When combined, they create a binome (a two-syllable word) where each element reinforces the other, resulting in a formal term meaning "to be subordinate to," "to be under the jurisdiction of," or "affiliation," often used in administrative, legal, or organizational contexts to describe a clear hierarchical relationship.
