This article analyses some characteristics of the kinship system among Toba groups of the Argentinean Chaco. We study the vocative and reference terminology of consanguine and affins and we analyze kinship system ascpects which oscillate between a centripetal tendency and an openness to the margins of the cognatic family relations for the sake of consolidation of a body of relatives more or less stable throughout generations. The cases studied here add some new ethnographic elements to the discussion about endogamy and exogamy in the Grand Chaco's groups.
