四合院(the quadrangle )是中国的一种传统合院式住宅。一个标准的四合院通常由一个庭院及其四周独立的房屋构成。不同方位的房屋有着不同的名称。坐北对着庭院入口处的称为正房（main house)，东西两边的称为厢房(side house)，坐南朝北的称为倒座房(reversely-set house)。长辈或一家之主住正房，晚辈住厢房。倒座房可以用作厨房、储物间、客厅或书房。四合院如今已经成为观光景点，并为世界各地的游客所熟知。
The quadrangle is a traditional courtyard residence in China. A standard quadrangle usually consists of a courtyard with independent houses along its four sides. Houses in different directions have their own names. The house on the north facing the courtyard’s entrance is called the main house; the house which lies on the east or west is called the side house; and the one stands on the south is called reversely-set house. The older generation or the head of the household lives in the main house, while the younger generation lives in the side houses. The reversely-set house can be used as a kitchen, a storeroom, a sitting-room or a study. The quadrangle has now become a tourist attraction and is well-known to tourists from all over the world.
