The E De live in houses built on stilts. These houses are generally elongated. The interior of the house is divided into two parts. The main part, called the Gah, is reserved for receiving guests. The rest of the house (called the Ok) is divided into compartments for a kitchen and for living quarters. At each side of the house there is a floor yard. The yard lying in front of the entrance is called the guest yard. Matriarchy prevails in E De society. Women are the heads of their families. The children take the family name of the mother. The right of inheritance is reserved only for daughters. The husband comes to live at his wife's house after marriage.
