greatnephew

A great-nephew is a male descendant who is the child of one’s nephew or niece. In generational terms, this places the great-nephew two generations below the person in question.

Alternative terminology exists: some sources use grandnephew to denote the same relationship, while others reserve “great-nephew” for a further generation. The female equivalent is a great-niece.

In common usage, these terms describe family connections rather than legal status, and they are primarily used in informal or genealogical contexts. The concept is relevant in family trees, obituaries, and discussions of lineage.

Example: If a person has a brother who has a son (that son is the person’s nephew), and that nephew has a son, that son is the person’s great-nephew. This relationship is defined by blood and generation distance, not by marriage or formal designation.
