1. A circular dwelling consisting of one room used by the Navajo Indians of North America: "Jane read an article about hogans which indicated that the entrances normally faced to the east, were made of wooden logs or stones, and the dome-shaped roofs were covered with mud and had holes in the tops to let smoke go out from the fires burning inside; and they were just like the ones she had seen during the school field trip the day before."
2. Etymology: from Navajo, hoghan, "house".
