Hall is a special place where people can walk, sit, and talk to each other. It is usually a big open space that connects different rooms in a building. Imagine it like a giant hallway in your house, but much bigger and sometimes with special decorations or fancy carpets. When you walk through a hall, you can see all the other rooms around you and people passing by. It's like a big meeting place where everyone can gather and move around easily. It's a very important part of a building because without it, it would be hard to get from one place to another. So, a hall is like a big open space that connects different rooms and allows people to move through a building easily.
