Kin Groups and Descent. Segmentary tribal structure and unilineal descent define Pathan kin groups. Genealogical and geographic divisions generally coincide. The most pertinent division within the tribal structure is the clan subsection, that is, the children of one man, generally encompassing four or five generations. It is within this sphere that one marries, makes alliances, and is in conflict. The smallest unit is the kor , or household, and it implies cohabitation with a living grandfather. This is the major economic and social unit; its members may cohabit in a village, a single compound, or a nomadic group. Descent is patrilineal.
Kinship Terminology. Aspects of the Eskimo system, in which avuncular and cousin terms are uniform, are present, though certain collaterals are distinguished. For example, while all other female cousins carry the same term as do all other male ones, the father's brother's daughter (potential or preferred bride) and father's brother's son (rival for Inheritance and thus potential enemy) are given distinct terms.
