The word 实施 is formed through the logical combination of two independent characters: 实 (shí), meaning "actual", "solid", or "real", and 施 (shī), meaning "to carry out", "to execute", or "to apply". Their compounding follows a standard modifier-verb structure where 实 acts as an adverbial modifier describing the manner, "in a real/substantive way", of the action denoted by 施, "to carry out". Thus, the compound naturally conveys the unified concept of "to implement" or "put into actual practice", where the first character qualifies the concrete nature of the action expressed by the second.
