The Chinese word 梦境 (mèngjìng), meaning "dreamworld" or "dreamlike state", is a compound noun formed by combining two meaningful characters: 梦 (mèng), which means "dream", and 境 (jìng), which means "boundary", "realm", or "state". It follows a common modifier-head structure in Chinese word formation, where the first character 梦 modifies and specifies the type of 境 (realm), thus creating the semantic meaning of "the realm/state of dreams". This construction is analogous to how English compounds like "daydream" or "dreamland" work, where two independent concepts merge to create a new, specific meaning.
