The Chinese word "敌军" (díjūn) is a compound noun formed by combining two individual characters: "敌" (dí), meaning "enemy" or "hostile", and "军" (jūn), meaning "army" or "military forces". It is structured as a modifier-head compound, where the first character "敌" acts as an attributive modifier describing the type or nature of the second character "军". Thus, the term literally translates to "enemy army" and functions as a single lexical unit referring to hostile or opposing military forces.
