Exogamy

Exogamy is a social arrangement where marriage is allowed only outside of a social group. The social groups define the scope and extent of exogamy, and the rules and enforcement mechanisms that ensure its continuity.

In social studies, exogamy is viewed as a combination of two related aspects: biological and cultural.
Biological exogamy is marriage of non blood-related beings, regulated by forms of incest law. A form of exogamy is a dual exogamy, in which two groups engage in continual wife exchange.
Cultural exogamy is the marrying outside of a specific cultural group.

The opposite of exogamy is endogamy, a marriage within a social group.
