The word **持械** is a verb-object compound formed through classical Chinese grammatical patterns, where **持** (chí, meaning "to hold" or "to wield") functions as the verb, and **械** (xiè, meaning "tool" or specifically "weapon") acts as its object. Together, they combine to create a specific legal and descriptive term meaning "to be armed with a weapon" or "to carry a weapon." This formation follows the common Chinese lexical process of combining two meaningful characters to produce a precise, often formal, term whose meaning is directly derived from the sum of its parts, typically used in contexts like law enforcement, legal documents, or news reports to describe armed criminal activity.
