Matrilineal sib is a term that refers to a group of related individuals that trace their ancestry through the female line. In some cultures, such as those in Africa, matrilineal sibs are highly valued and form the basis of social organization. However, the term matrilineal sib may not be familiar or may be difficult to pronounce for some people. There are several synonyms that describe the same concept, including matriclan, mother-right group, matrikin, matrilineal clan, and matrilineal kinship group. These terms are frequently used in anthropological and sociological research to describe the social and cultural organization of communities that trace their lineage through women.
