A "façade" refers to the front or exterior surface of a building, often designed to be visually appealing. It can include elements like windows, doors, and decorative features that contribute to the overall architectural style. The façade is important in creating the first impression of a structure and can reflect the cultural or historical context of its design. In a broader sense, the term "façade" can also describe a deceptive outward appearance. For example, a person might present a cheerful façade while feeling sad inside. This usage highlights the contrast between how things appear and their true nature, similar to the way a building's exterior may not reveal its internal structure or function.
