Penthouse

[석수]

“Penthouse” originally referred to an attached, sloping shed or awning. The word stems from Old French (apentis) and Latin (appendere, meaning "to hang").

By the 1500s, the spelling was altered through "folk etymology" to resemble the word "house" and the French word for slope, pente.

Here is how the definition evolved:

14th to 19th Century (Attached Shed):

The term initially described a simple, sloped outbuilding or awning. Early Middle English homilies even reference a "penthouse" as the makeshift stable where Jesus was born.

Early 20th Century (Roof-top Apartment): With the early 1900s boom in skyscraper construction, the word transitioned to describe the structure (originally just an elevator housing or small equipment room) built on the roofs of tall buildings.

Modern Era (Luxury Living): Following World War I, these roof-top structures were expanded into luxury living spaces, giving the word its current connotation of a high-end, top-floor residence.You can read more about the word's full transition on the Online Etymology Dictionary or explore its architectural evolution via Wikipedia's Penthouse apartment article.
