The word “mansion” comes from the Old French word maison, which means “house” or “dwelling.” This, in turn, derives from the Latin word mansio, which originally meant “a staying, dwelling, or abiding.” The Latin verb manere, meaning “to remain” or “to stay,” is the root of mansio.

In medieval times, the term “mansion” began to be associated with larger, more elaborate homes or estates, particularly those of nobility or the wealthy. Over time, the word came to signify a large and impressive house, often associated with grandeur and luxury.
