The Chinese word 弹药 is formed through the semantic fusion of two characters: 弹, which denotes "bullet" or "projectile", and 药, which originally means "medicine" but in this context refers to "gunpowder" or "explosive material". By combining these elements, the word conceptually represents the complete assembly of ammunition, where 弹 is the projectile that is propelled or discharged, and 药 is the propellant or explosive charge that enables its function, thus encapsulating the dual components essential to its operation in a single term.
