ættaðar
Ættaðar is an Icelandic term used in genealogical and historical contexts to denote people who are descended from a common lineage or family. The word derives from ætt, meaning lineage or clan, and is used in an inflected form to indicate membership in that lineage. In practice, ættaðar appears in genealogical lists, sagas, and historical records to distinguish blood relatives from individuals connected by marriage or alliance. The concept encompasses kinship by blood and is often employed when tracing ancestry to identify those who belong to the same stock or family line. The term is related to other words such as ætt (lineage) and ættfræði (genealogy). In modern Icelandic usage, ættaðar is primarily seen in historical or scholarly writing, while everyday language may employ more common expressions for kinship. Overall, ættaðar reflects a traditional emphasis on ancestral descent and the tracing of family lines within Icelandic literary and documentary sources.
