The Chinese word "锁门" is a straightforward verb-object compound, formed by combining the verb "锁" (suǒ, meaning "to lock") with its direct object "门" (mén, meaning "door"). This syntactic structure, where an action is directly followed by the thing receiving the action, is highly productive in Chinese for creating concise phrases that describe a complete action. Therefore, "锁门" literally and functionally means "to lock the door", representing a single, specific task formed through the logical pairing of an action and its target.
