An Arizona room is like a special little room that exists in some houses in Arizona. It's a room that is usually connected to the back of the house and has big windows or doors that let in lots of sunlight. It's called an Arizona room because it's designed to help people stay cool in the hot desert climate of Arizona. The idea is that you can relax in this room and enjoy the sunshine without getting too hot. Some people also use Arizona rooms as extra living space or a place to entertain guests. It's a little bit like having a sunroom or a screened-in porch, but it's designed specifically for the Arizona climate.
