parallelcousin

A parallel cousin is a child of an aunt or uncle who is the parent's opposite-sex sibling. For example, a child of your father's sister is your parallel cousin. This is in contrast to a cross-cousin, who is the child of an aunt or uncle who is the parent's same-sex sibling. For instance, a child of your father's brother would be your cross-cousin. The distinction between parallel and cross-cousins is significant in some kinship systems, particularly those that emphasize patrilineal or matrilineal descent. In such systems, marriage rules may differ depending on whether an individual is considered a parallel or cross-cousin. While the term "parallel cousin" is not as commonly used in Western cultures, the concept is fundamental to understanding kinship structures in many other societies. The terms reflect a way of categorizing relatives and can influence social obligations, inheritance patterns, and marriage eligibility.
