Omaha kinship terminology is one of the six major kinship-terminology systems Lewis Henry Morgan classified, first studied together with the Crow system in 1859 and formally set out in his 1871 Systems of Consanguinity and Affinity of the Human Family. It is found in patrilineal societies and is structurally close to a mirror image of the matrilineal Crow system: on the father's side, relatives are grouped by sex and generation as usual, but on the mother's side the terminology collapses generational distinctions, a pattern called patrilineal skewing, so that the mother's brother, the mother's brother's son, and the mother's father can all be grouped under a single term regardless of the actual generation gap between them. The system is named for the Omaha people and has also been documented among the Dani of New Guinea, the Igbo of Nigeria, Indigenous groups in Mexico, the Mapuche of Chile and Argentina, and the Shona of Zimbabwe; some linguists have proposed it as the reconstructed pattern underlying Proto-Indo-European kinship.

Facts
Descent RuleSourced to the subject's own accountAssociated with patrilineal descent: relatives on the father's side keep distinct generational terms, while the mother's side is skewed, collapsed into single terms spanning multiple generations, the mother's brother, the mother's brother's son, and the mother's father can share one term; the mirror image of the matrilineal Crow system. 1 Descent RuleSourced to the subject's own accountCross-cousins are shifted a generation depending on which parent links them: a mother's brother's children are addressed with the terms for mother's brother and mother herself, while a father's sister's children are addressed with the terms used for one's own children. 1 Typical RegionSourced to the subject's own accountNamed for the Omaha people; also documented among the Dani of New Guinea, the Igbo of Nigeria, Indigenous groups in Mexico, the Mapuche of Chile and Argentina, and the Shona of Zimbabwe; proposed by some linguists as the reconstructed Proto-Indo-European pattern. 1 Descent Rule

Held Differently
Structurally close to a mirror image of the matrilineal Crow system: the same generation-collapsing logic applied to the opposite, non-descent, side.

Entity-backed identity for the descent-rule category this kinship system already carries as an enum fact, resolved to a kinship-system entity by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The enum fact itself stays on the entity unchanged.

Studied By
The Omaha kinship terminology system, the structural mirror of the Crow system under patrilineal rather than matrilineal descent, is one of the six classificatory systems Lewis Henry Morgan defined.

In this system, relatives are sorted according to their descent and their gender.

Kinship system section, cross-cousin generational shift paragraph
On the maternal side, cross-cousins are raised a generation (making them Ego's Mother's Brother and Ego's Mother), while those on the paternal side are lowered a generation (making them the generational equivalent of Ego's Children).
