The Chinese word **庭院** (*tíngyuàn*) is a compound term formed by combining two semantically related characters: **庭** (*tíng*), which originally denotes the main hall or front courtyard of a traditional compound, and **院** (*yuàn*), which refers to an enclosed space, courtyard, or institution. Together, they create a **binomial or coordinate compound** where each character reinforces and specifies the meaning of the other, resulting in a term that broadly means "courtyard" or "enclosed garden yard," often evoking the image of a private, walled outdoor space adjacent to a dwelling, characteristic of traditional Chinese architecture.
