The Chinese word **墓碑 (mùbēi)**, meaning "tombstone," is a compound noun formed through semantic combination. It consists of two meaningful characters: **墓 (mù)**, which means "tomb" or "grave," and **碑 (bēi)**, which means "stone tablet" or "stele." In Chinese word formation, this is a typical **modifier-head structure**, where the first character **墓** specifies the location or purpose, and the second character **碑** denotes the core object. Therefore, the compound literally and logically means "a stone tablet for a tomb."
