The word 枪杀 is formed by combining two characters: 枪 (qiāng), meaning "gun", and 杀 (shā), meaning "to kill". It is a direct and logical conceptual fusion where the first character specifies the instrument or method, and the second character states the core action. Together, they create a single, compound concept that means "to shoot and kill" or "to kill with a gun", efficiently conveying a specific violent act through this instrumental-action pairing.
