Structural variables differentiating kinship identities, such as sex, generation, and type of relationship (lineal, collateral, conjugal), are reflected in sentiments about family identities. In particular, componential variations in kinship terms predict Evaluation, Potency, and Activity ratings of the terms fairly accurately. Between 44 and 92 percent of the variation in the sentiment measures is explained by regressions on componential variables. This means that the cognitive distinctions employed in American kinship terminology correspond closely to sentiments held toward those social locations. (Contains 6 tables and 18 footnotes.)
