- Moieties divide a society into two unilineal descent groups, often serving complementary functions.

- Phratries are larger groups that consist of several clans with a common mythical ancestor.

- Clan:

- A clan is a group claiming common descent from a distant or legendary ancestor, often without precise genealogical links.
