Pronunciation: [ɛntɹˈɛsɒl] (IPA) 
The word "Entresol" is a French architectural term that refers to a mezzanine floor between two main levels. It is pronounced /ɑntrəˈsoʊl/ and spelled with an "e" at the beginning, not an "a". The "e" at the beginning of the word is a French article (meaning "the"), and the "s" is pronounced as a "z." While the word may be unfamiliar to many English speakers, it is commonly used in the context of interior design and architecture.
An entresol, also commonly known as a mezzanine or an intermediate floor, is a semi-floor situated between two main levels of a building. Typically, it is inserted within a building's floorplan to provide additional space without devoting an entire floor to it. The entresol is usually positioned between the ground and first floors, creating an intermediary level that is often smaller in size compared to the surrounding levels. It serves as a connecting link between the two main levels and can be further used for various purposes.
Historically, entresols were commonly found in grand houses and palaces, where they were utilized for functions such as housing servants, storage, or extra rooms. Nowadays, entresols are a popular architectural feature in commercial buildings and retail spaces, particularly in shopping malls and department stores, where they are commonly utilized as retail areas or food courts.
In terms of design and structure, an entresol is generally characterized by having a low ceiling height in comparison to the other floors. This reduced height allows for a smooth integration of the additional level within the overall architectural layout of the building. The entresol is often accessed through staircases or elevators connecting the main floors, making it easily accessible to visitors or occupants.
In summary, an entresol serves as an intermediate floor that bridges the gap between two key levels within a building's structure, providing extra space and functionality while maintaining a cohesive architectural design.
In arch., a low room or apartment between two floors.
