Kin Groups and Descent. The Tewa of New Mexico reckon kinship bilaterally, while the Hopi-Tewa of Arizona are matrilineal. The kinship grouping of the New Mexico Tewa reflects their dual social organization, which consists of nonexogamous nonunilinear moieties: every Tewa belongs to either the Winter or Summer moiety. These moieties are the largest kin groups for the Tewa; however, moieties are more than kinship entities (see below). Hopi-Tewa society is divided into exogamous Matrilineal clans.
Kinship Terminology. Tewa kinship terms are mostly descriptive and generational and designate the precise relationship to a speaker. Hopi-Tewa terms follow the Crow system.
