A hall is the space in a house or building that leads to individual rooms. Some homes are organized with several bedrooms leading off one long hall.
Your house might have a front hall just inside the main door, or if you live in an apartment building, your door might be at the end of a hall on the fourth floor. Another kind of hall is a large room meant for holding events, like a village hall, exhibition hall, or lecture hall. College campuses often include many halls — these are commonly dormitory buildings, which include hall in their names.
