Kinship terminology plays an important role in Boro society, representing both family relationships and broader social connections. They represent not only close relationships with family, but also cultural values and social ideology of the Boro community. They also express a sense of responsibility, love and respect for one another. Kinship terms are identified chiefly on marriage and blood (descent) relation. This is a traditional means of family relationship and unity that is valued within Boro culture and society. The kinship terms may be analyzed in terms of linguistic structure. They may be classified into two sub-categories: terms of address and terms of reference. Terms of address are used in direct interactions. To construct terms of address, kinship terms are combined with the first-person pronoun to express relationships. In contrast, terms of reference are used to express the kinship relationship indirectly. In this case, kinship terms are combined with second and third person pronouns. This study chiefly aims to explore the linguistic structure of Boro kinship terminology and its relevance in identifying familial and kinship relationships within a social context.
