        Terms Agnatic: 
        Descent traced through males (sometimes misleadingly termed "patrilineal")Uterine: Descent traced through females (sometimes termed "matrilineal")
 Agnates: "Male or female descendants by male links from the 
        same male ancestor" (Schusky)
 Uterine Kin: Male or female kin linked to ego through female links
 Bilateral: "A practice which links a person with a group of 
        close relatives through both sexes" (Schusky) (sometimes also termed 
        "cognatic")
 Cognatic Kin: Relatives by "blood" without particular 
        emphasis on male or female links
 Unilineal Descent: The tracing of relationship through either the 
        male or female line
 Bilineal Descent: The tracing of relationship through both male 
        and female links
 Double Descent: An individual belongs to one group through agnatic 
        descent, another through uterine descent; frequently different types of 
        property and rights are passed through the two sexes.
 Group: Set of persons who meet regularly, are self-aware of their 
        membership
 Corporation: A property-holding unit, never dies
 Unilineal Descent groups (UDG): Group of persons recruited on the 
        basis of links through one sex; lineages and clans are examples
 Lineage: "A consanguineal kin group practicing unilineal descent, 
        which includes only persons who can actually trace their relationship 
        to a common ancestor; that is, a lineage is all the unilineal descendants 
        of a known common ancestor or ancestress" (Schusky)
 "Nuer lineages are not corporate, localized, communities, though 
        they are frequently associated with territorial units
" (Evans-Pritchard)
 Clan: "A clan may be defined as a group of persons of both 
        sexes, membership of which is determined by unilineal descent, actual 
        or putative
 the clan may consist of a group of lineages" (Notes 
        & Queries): "in a lineage group each member can actually, or 
        at least theoretically, trace his genealogical connection with any other 
        member by descent from a known common ancestor, connection with any other 
        member by descent from a known common ancestor, whereas in a clan
 
        this is not possible
 it is usual to apply the term clan 
        to both patrilineal and matrilineal groups, but some American ethnographers 
        use the term clan only for matrilineal groups and gens 
        for patrilineal
" (Radcliffe-Brown)
 Patrilineage: Lineage based on links through males (composed of 
        both sexes)
 Matrilineage: Lineage based on links through females (composed 
        of both sexes)
 Segments: "Each male member of a patrilineage is himself the 
        potential founder of a lineage of his own, which then forms a branch or 
        segment of the original lineage. Thus in some societies each lineage is 
        a segmented group, divided into major segments each of which is divided 
        into lesser segments
" (Barnes). (The three usual terms are 
        maximal [largest] major -minimal).
 Segmentary: "A merging series of subgroups of increasing inclusiveness, 
        two groups that stand in contraposition at one level of segmentation merge 
        when opposed to a group of a higher order of segmentation" (Goody). 
        When centralized administration is absent these are known as "segmentary" 
        (or acephelous  without a head) societies.
