The Chinese word 做主 is formed as a verb-object compound, where the verb 做 (zuò, meaning "to do" or "to act as") is combined with the object 主 (zhǔ, meaning "master" or "host"). Literally, the phrase means "to act as the master", and through this metaphorical construction, it has evolved into the common verb meaning "to decide", "to be in charge", or "to have the final say". This formation illustrates a typical pattern in Chinese where an action verb is paired with a nominal element to create an idiomatic expression denoting a specific role or function, in this case, the act of taking authority or responsibility for a decision.
