facade
The front face of a building, like its outer side.
A facade (pronounced fuh-SAHD) is the front face of a building, especially an impressive or decorative one. When you walk down a city street and look at storefronts, grand museums, or historic theaters, you're looking at their facades. Architects design facades to make buildings attractive and welcoming, using columns, windows, ornamental details, and different materials like stone, brick, or glass.
The word also describes something that looks good on the outside but hides a different reality underneath. When someone puts on a facade of confidence, they act self-assured even though they feel nervous inside. A bully might maintain a facade of toughness to hide insecurity. A struggling business might keep up a facade of success by decorating its offices expensively.
This second meaning isn't always negative. Sometimes a facade protects us while we work through difficulties. A student dealing with problems at home might maintain a calm facade at school so they can focus on learning. The key question is whether the facade helps you move forward or prevents you from being honest about problems that need solving.
