crosscousin

A cross-cousin is a child of one's parent's sibling of the opposite sex. Specifically, it refers to the child of a father's sister or a mother's brother. This contrasts with a parallel-cousin, who is the child of a parent's sibling of the same sex (i.e., the child of a father's brother or a mother's sister).

The distinction between cross-cousin and parallel-cousin is significant in many kinship systems and has implications for marriage rules. In some cultures, marriage between cross-cousins is preferred or even prescribed, while marriage with parallel-cousins is forbidden. This practice is often linked to the exchange of goods, services, or people between kin groups, helping to maintain social alliances and economic ties.

The specific terminology used to refer to cross-cousins can vary widely across different languages and cultures. While the English term "cross-cousin" is a general anthropological concept, local terms may reflect the specific genealogical relationships and social roles associated with these individuals. The concept of cross-cousin marriage is a key area of study in cultural anthropology, particularly in understanding kinship structures and marriage patterns in diverse societies.
