Marriage. Social status and kinship are the two factors most influential in regulating marriage. The castelike groups form two pairs of endogamous units: the smiths and leatherworkers constitute one unit, the praise singers and former weavers the other. In addition, the higher-ranking "nobles" and the lower-ranking "slaves" each form endogamous groups. But a "noble" man may marry a "slave" woman under special circumstances. Bilateral cross-cousin marriage is the preferred form, with priority given to marriage between a man and his mother's brother's daughter. Parallel-cousin marriage was once forbidden, but this prohibition is no longer in force. According to Islamic law, a man may have up to four legal wives, and in fact about 45 percent of Wolof men have at least two wives. Sororate and levirate are still practiced. The basic marital residence pattern is patrilocal, although there are some cases of temporary avunculocal residence. Divorce is rather frequent.
Domestic Unit. The main residential group may or may not constitute an integrated household. It is often composed of more than one family unit. Family units that form a single cooking unit and eat together constitute a single domestic unit. Separate domestic units tend to be established within a residential group when there have been disputes between family units or when one of the family units is of a lower social rank and unrelated to the others.
Inheritance. Both inheritance of material goods and succession to important kinship and political roles are determined patrilineally. The Wolof divide these goods and roles into two categories, nombo and alal. The former term is associated with land, wives, and social positions such as the headship of a residential group, of a patrilineage, or of a village, each of which passes first to a man's brother, secondly to his father's brother's sister, and only when none of these are left do they pass to his son (all but the wives). The term "alal" applies to money, cattle, and houses, which are inherited directly by a man's sons. (Formerly, slaves were also "alal.") As for matrilineal inheritance, it is believed that if the mother is a witch, the children will be witches. If only the father is a witch, the children will be able to see into the witches' world but will not actually be witches.
Socialization. Children are weaned at about 1.5 to 2 years of age, and are carried on the mother's back until that time. Boys live in their mother's hut until they are circumcised at about 8 to 12 years of age. Physical punishment of children is strongly disapproved of and rarely inflicted. Some children attend primary schools, which are available in the larger villages.
