The Chinese word "开枪" is formed by combining the character "开", meaning "to open" or "to initiate", with "枪", meaning "gun" or "firearm". This compound directly illustrates the concrete action of initiating the discharge of a gun, where "开" conveys the act of triggering or starting, and "枪" specifies the object involved, resulting in the meaning "to open fire" or "to shoot". The formation is a straightforward conceptual blend of an action verb and its tool, reflecting the physical process of firing a weapon.
