The word "facade" refers to the outward appearance or front of a building, especially one that is decorative or designed to impress. More broadly, it can also mean a deceptive outward appearance that conceals a less pleasant reality. For example, someone might put up a facade of confidence while actually feeling insecure.
The term "facade" comes from the French word "façade," which means "face" or "front." It is derived from the Italian "facciata," originating from the Latin "facies," meaning "face" or "form." The word has been in use in English since the early 18th century.
