A hallway is a passage or corridor in a building that connects different rooms.
You'll often find hallways in homes, offices, and schools. They can be long and straight, short and curved, or even narrow staircases. Hallways are usually where you walk through to get from one room to another - like from your bedroom to the living room. Imagine going into a house and looking for the bathroom; you'd probably go down the hallway first. Some hallways have doors leading off them, while others might just be lined with pictures or decorations. Hallways can also be pretty long, so they might have some sort of lighting or features like clocks or mirrors to make it easier to navigate.
