What are corridors commonly known as?

Corridors are commonly known as passageways because they serve as pathways that lead from one area to another within a building or structure. Passageways facilitate movement, allowing people to travel between rooms or sections without obstruction. This term connotes the function of a corridor, which is to connect separate spaces while often being narrower than the adjoining rooms.

While hallways might also refer to similar spaces, the broader term "passageways" encompasses a variety of configurations and uses, making it the most accurate option in this context. Rooms and entrances, on the other hand, refer to different structural components; rooms are enclosed spaces, and entrances are points of access into a building or room. Thus, "passageways" effectively captures the essence and role of corridors.
