shack

v. live together without being legally married (Slang)

n. hut, shanty, small poorly built cabin

A shack is a type of small house that is in disrepair. The word may derive from the Nahuatl (Aztec) word xacalli or "adobe house" by way of Mexican Spanish xacal/jacal, which has the same meaning as "shack"[1]. It was a common usage among people of Mexican ancestry throughout the U.S. southwest from the 18th century if not earlier. Shacks are often not settled, however in the developing world it is often used as shelter.
