what is a sukkah used for

A sukkah is a temporary hut constructed for use during the week-long Jewish festival of Sukkot. It is a structure consisting of a roof made of organic material which has been disconnected from the ground for the purpose of the commandment (the schach). A sukkah must have three walls, be at least three feet tall, and be positioned so that all or part of its roof is open to the sky. Only the part which is under the sky is kosher. Most authorities require its floor area to be at least 16 square cubits. The sukkah is meant to be a place for outdoor dining, and it is customary to sleep in the sukkah all week, though not everyone does the sleeping part. During the holiday, Jewish people spend time in the sukkah, treating it like their home, and it is traditional to decorate the sukkah and hang fruit and fragrant plants inside. Weather permitting, meals are eaten in the sukkah, and some people even choose to sleep in the sukkah. The sukkahs purpose is to commemorate the time the Israelites spent in the wilderness after they were freed from slavery in Egypt.
