The Vietnamese word "kiến trúc sư" translates to "architect" in English. An architect is a professional who designs buildings and other structures. They plan how a building will look and function, taking into account safety, aesthetics, and the needs of the people who will use the space.
In Vietnamese, "kiến trúc" by itself refers to the field of architecture, while "sư" can be used in other contexts to refer to a master or expert in various fields, not just architecture.
