Facade

In general knowledge, a "facade" refers to the outward appearance or front of something, often used to describe a deceptive or misleading impression. It originates from architecture, where it denotes the front of a building. In broader contexts, such as psychology or social interactions, it can signify a superficial layer that hides a deeper reality. For instance, someone may present a cheerful facade while struggling with personal issues behind the scenes. Essentially, it highlights the difference between how things appear and how they truly are.
