This study explores the nature and solution of family conflict in the patrilineal-genealogic clan of Manggaraian society based on the conceptualization ascribed in their cognitive map, as reflected in the forms and meanings of linguistic phenomena they employ in the traditional expressions of Manggaraian language as the mirror of Manggaraian culture. The study is descriptive-qualitative. The theoretical framework is cultural linguistics, one the new theoretical perspectives in cognitive linguistics exploring the relationship between language, culture, and conceptualization. The results of study show that nature of family conflict occurring in Manggaraian patrilineal-genealogic clan is an internal problem in a household (rintuk tau lewing agu kebor) and, as such, there is no need to involve external parties to solve it. The approach to solving the problem is win-win solution (hambor) as the parties involved in the family conflict are declared right and the clan leader is declared wrong as he is negligent in doing precauitions to prevent conflict (anggom). As they are of the same clan, it is difficult for the clan leader to detemine which party is right or wrong (paki cala wa’i, tuku cala tu’us). The solution of family conflict is carried out through local-democratic model (lonto leok) aimed at maintaining social harmony between the members of wa’u as a patrilineal-genealogic clan. The study is beneficial to preserve the traditional expressions of Manggaraian language as the forms and meanings of linguistic phenomena used imply a set of local wisdoms inherited from the ancestors of Manggaraian society serving as the frames of reference for them in organizing their patterns of behavior in the contexts of living together as the members of the wa’u as a patrilineal-genealogic clan.
