The word 山顶 (shāndǐng), meaning "mountaintop" or "summit", is a typical Chinese compound word formed through the combination of two meaningful characters: 山 (shān), meaning "mountain", and 顶 (dǐng), meaning "top" or "peak". It follows a modifier-head structure, where the first character 山 specifies the type of object, and the second character 顶 denotes the specific part or feature of that object. This logical and semantic construction directly describes the highest point of a mountain, making it an efficient and intuitive example of how Chinese creates new words by combining existing, concrete concepts.
